Tech Views — Vol. 3 Mirrors

Are you aware of the major differences between mirrors?
"Mirrors? I think they're okay for just seeing what's behind."
This sort of thinking is a big mistake. Riders get many types of information from their mirrors, and all are important.
"All mirrors are pretty much the same, no matter who makes them."
If you believe this, then you're also making a big mistake. Some mirrors are easy to view and some are not, and this can depend on both manufacturer and model.
In this chapter, we'd like to confirm just how particular Honda is about mirror visibility, and come to understand some of the aspects of performance that are not so easily described in catalogs. Aspects of performance that make riding more enjoyable.
As rider and journalist Tsutomu Matsui discovered, "Mirror visibility should also be an important concern when buying a motorcycle."
Just being able to see correctly... That's where their value lies.
Are you aware of the major differences between mirrors?
The information we get from our mirrors -
When riding a motorcycle, this source of information is often just as important as the view ahead.
Like that 'view,' I think that a mirror's usability and range of adjustment also factor in among the many important performance features riders rely on.
Mirrors can be round, square, or other shapes, and mounted in many different ways, from handlebar-mounted types to those attached directly to a fairing or cowl. A wide range of types and styles are also available, but one truth remains: Easy-to-see mirrors make one's riding experience richer and more enjoyable.
Although some aftermarket mirrors might look cool or be designed with an emphasis on styling, mirrors that give an unsatisfactory view of what's behind are more stress-inducing than most people imagine. My feeling, based on many years of riding experience, is that riders should focus more on a mirror's degree of visibility than its physical appearance or how cool it looks.
So, what are the standards for this 'Degree of Visibility'?
Most countries have laws governing the safety aspects of vehicles using public roads. In Japan, for instance, many items related to motorcycle rearview mirrors, including mirror surface area, degree of visibility, adjustment ease, and collision safety, etc. are strictly regulated. Rules, of course, differ from country to country, but any motorcycle sold in an authorized dealership has met all such local legal requirements.
It therefore follows that every new bike from around the world that I've ever encountered complies with these standards. However, as noted earlier, depending on make and model, some mirrors are 'easy-to-see,' and others are not. I think this gives a clear understanding of a manufacturer's basic philosophy.
In this chapter, I've set out to reconfirm this important part of design philosophy.
In the City
Like most people, I use various forms of transportation to move comfortably through the city. In my early teens, I used to ride everywhere by bicycle. As someone who started riding motorcycles at the age of 17, I find the motorcycle's range of mobility and comfort to be its primary sources of enjoyment, and things that I can't compromise on.
Cities are populated by people of many ages who use many means of transport for innumerable reasons. People ride bicycles, drive cars, or walk as well. Cities have always been bustling societies of mixed movement. For this reason among many, good rearward visibility is often just as important as keeping a steady eye on the road ahead. Even when changing lanes to keep a safe distance from pedestrians, the rearward visibility of the mirrors plays a crucial part in allowing me to instantly make my decision to move.
It's interesting that at first glance mirrors all look pretty much the same. However, the degree of visibility they provide can differ greatly from vehicle to vehicle. What's the situation with, for instance, a scooter made to get around the city, like the Honda PCX with its relaxed riding position? The PCX's mirrors provide an ample visual field, and when on the move their clear visibility is almost completely unaffected by vibration. Critical visual information is there at a glance, from edge to edge across both mirrors, and the images reflected provide a good sense of the distance to following vehicles. I was especially pleased by how easy they were to adjust, and my level of satisfaction with these mirrors was high in all respects.
The PCX also delivers up an impressive degree of luxurious riding comfort for a 125cc class scooter, and seats two easily. I cruised the streets in the vicinity of my home with one of my family riding on back. This precious bit of time together brought smiles to both our faces. Even then, the wide range of clear visibility offered by the PCX's mirrors enabled me to enjoy this comfortable ride with complete peace-of-mind. Also, when carrying passengers, it certainly doesn't hurt to be able to see their faces, and really all mirrors should do this.
The SH Mode is another lively scooter for getting around town, and I could feel my back straighten up whenever I climbed aboard. From this upright posture, I felt like I was looking down a bit toward the mirrors. However my arms never came into reflected view, even when leaning close to the mirrors. Their degree of visibility was exactly what I expected. Just a quick glance was enough to let me see what I needed.
Also, because the mirrors were so close, it only took a slight turn of the head to widen the field of view and keep an eye on traffic conditions behind and around me. The degree of visibility these mirrors offered was crisp and clear, and remarkably good.
Honda has a long, proud history of making slim big-wheeled scooters with upright riding positions, going back to the SH50 first introduced on the streets of Europe in 1993. On other Italian-made models I've ridden, the mirror stays are often long, and while they're easy to see with when stopped, on the move their inherent vibration makes for viewing difficult. However, both the PCX and SH Mode were thankfully free from these problems.
I also tried out the 250cc-class Forza scooter and CRF250L dual-sport bike. The Forza's big scooter mirrors were virtually unaffected by vibration, and I could see no significant difference in distance perception between vehicles approaching from behind and their reflected images in the mirrors.
While checking these points, something occurred to me. While we motorcycle journalists readily note a bike's equipment, storage space and other features when writing our articles, we should really provide more feedback on the quality of the mirrors and their degree of visibility. One reason is that Honda's deep interest in achieving such a high degree of visibility in their mirrors seems extraordinary compared to other manufacturers.
Dual-sport bikes like the CRF250L are often powered by single-cylinder engines, and in some cases the vibration felt in their steps, seat or tank can get to be quite an annoyance. In the case of single-cylinder models with relatively high handlebars, parts at the ends of the bars, such as grips and mirrors, can be especially susceptible to the effects of vibration and, paradoxically, these can be the best bikes to check for visibility. Although the CRF250L's mirrors are subject to the same sort of vibration, I didn't really notice it much from the standpoint of viewing ease. Even on a wide three-lane highway, I was able to accurately see what was both directly behind me and off to my sides.
On other makes of bikes, I've often noticed that the same mirrors are used year after year with no change in design. Although I understand that design in a matter of individual taste, I still think it might be best to occasionally update mirror designs in keeping with the times.
In terms of viewing ease, many such mirrors tend to force riders to move not only their eyes, but also their head, neck and more to get a clear view of changing conditions to the rear. Having to move one's body around to see what's behind shouldn't be necessary, and can be a bit unsettling. This also gives a clear indication that the mirrors are difficult to see with, and that their range of satisfaction is seriously lacking. With that perspective, my evaluation of the CRF250's mirrors confirmed that their level of performance was still quite high.
When I first began riding at the age of 17, I often replaced the original mirrors with other aftermarket brands that had what I thought were more attractive designs. I used to think of this as a first step toward customizing my bike, and didn't really give viewing ease much consideration. In other words, I often threw away the viewing ease that the original mirrors offered.
However, with more years of experience riding, I gradually came to learn that while keeping my eyes focused on the road ahead is an important premise of riding, seeking out places where I could really appreciate the grip of the tires on the road while taking in the vast space that surrounds me is also important.
Also, mirrors that simply look cool don't quite do the job. Instantly conveying critical visual information is the important job mirrors are assigned. Therefore, I've come to believe that we should all pay more attention to the mirrors we use and how the issues of visibility and viewing ease have been approached. As a rider, you've really got to be able to intuitively sense the difference. Based on my own experience, that's my advice.
The Touring Scene
When traveling long distances, a motorcycle makes everything you see around you all the more impressive. Although there may stretches of monotonous scenery, there are also times and scenes, like clouds in the sky, that remain vivid deep in your heart.
Besides giving riders an easy way to check rearward visibility, I've come to feel that mirrors also play an important role in touring by functioning as a sort of camera of the heart; helping me capture scenes that I might have missed while focusing on the road ahead, and allowing them to unfold in a profoundly inspiring manner.
In this way, the GL1800 Gold Wing's mirrors are superb. They not only perform the basic job of providing clear and wide-ranging rearward visibility, whatever the speed, but also allow the rider to instantly take in the scenery behind as it fades into the distance. It goes without saying that the Wing's mirrors are superbly made for the purpose of enjoying that rearward scenery. Their size and reflectivity offer just such a sense of spaciousness. In a sense, they stand out as the world's No. 1 touring mirrors.
While planning a bike comparison article like those often run in motorcycle magazines, I had the pleasure of riding the Gold Wing together with several other bikes of the same class. Riding together, it's easy to maintain a comfortable distance between bikes, and also to check to see if all are riding in formation. As I thought, the Gold Wing's mirrors really seem to be designed with various points of view in mind, and their creator's designer philosophy really stands out in these parts.
It was interesting to note how significantly the VFR1200F differs in style from the other bikes we were testing, even though they all qualified as tourers. Compact and stylish, its aerodynamic styling blends in well with its overall design. Yet, its mirrors aren't particularly small in size, at least as viewed from the rider's seat. The mirror surfaces aren't very tall, but are quite wide, so there's no sense of narrowness visible in their field of view. The positioning of the mirrors and their stays are excellent, achieving both cool styling and superb viewing ease; ideal for a bike designed to carry a rider long hours on an expressway leaned forward into the wind.
Whether wearing a thick winter jacket or a more tightly fitting leather jacket, visibility in both mirrors was excellent, and never compromised. I was also happy to find that they're easy to adjust. Speeding down the expressway, these mirrors really shine, providing an easy reading of rearward conditions that's a notable feature.
Among the other riding machines in this class made by other manufacturers, some seemed to be highly susceptible to engine vibration, and their blurred mirrors showed it. I couldn't help wondering why it was that none of the Honda models we tried suffered from this problem. This is a difference from their competition that really can't be seen in a photo, or detected on a showroom floor.
Some time ago I posed this question to one of Honda's development engineers, and he answered, "Honda has strict rules regarding mirror visibility, so I'm sure that our mirrors are a step above those of our rivals." However, this is something never covered in their catalogs, not to mention on the web site. Sometimes I think they ought to mount a pair of mirrors on the new RC213V racer at a MotoGP exhibition in order to demonstrate their visual performance, rather than simply stating, "These mirrors are good."
Sports Bike Mirrors Designed to Overcome a Difficult Problem
Sports bikes are styled to cut cleanly and smoothly through the air with a sensation of speed that mimics the racing machines, so their owners often prefer mirrors that are as small and unobtrusive as possible. I've had plenty of experience riding bikes like this. One I recall was certainly cool to look at, but I had to take my hand off the bars in order to see anything in the mirrors. Another forced me to contort my arms in order to use the mirrors. On bikes like these, even changing arm positions often doesn't improve the limited rearward visibility their mirrors provide, adding considerable unease to every ride.
Riding on winding roads while in the forward crouch common to sports bikes, you feel as though you're part of the machine. While enjoying this feeling of performance, the effort you have to make to see anything in the mirror, or just turn your head around to look, really takes away from that pleasant feeling. Since I'm not the only one using the road, I'm always concerned about who or what is behind me, no matter where I'm riding. Because of this, I feel it's important to be able to have that important information at a glance. Of course, even if the mirrors are easy to see with, if their stays are ugly stumps, I can't really recommend that either.
In this respect, I found the CBR600RR's mirrors to be highly functional, offering a clear view through the twisties of a winding mountain road. The road I was tracing seemed to reverse itself in the mirrors, and the stays, I have to say, were beautifully designed. The adjustment range for these mirrors was also quite wide, and I was able to find the best positioning for whatever riding I was doing in a very short time.
The winding road I took is quite a long ways from home, so I took the roads leading there in touring bike style. In town, at the foot of the mountain pass, I maneuvered through crowded city streets like I was riding a scooter, sharing the road with cars and pedestrians. Cool practicality is of the utmost importance in these situations.
From time to time, certain super sports machines become benchmarks of their class. Clear yardsticks of circuit speed or best operation in a complete package, etc. If mirrors were ever to become a point of comparison with its rivals, I think the CBR's mirrors would obviously be the benchmark. I came to this conclusion while riding a rival machine, when I suddenly felt that the view from its mirrors "just isn't the same."
In Conclusion
In this way, I came to more clearly understand that all Honda mirrors have been carefully developed through meticulous study of user tastes and requirements. Position, adjustment ease, wide rearward visibility and ease of reading traffic conditions - these are the features you turn to whenever you ride a bike you've bought. As distinct from the catalog specifications as other factors you compare before buying, such as handling, engine power characteristics, parts quality, the complete package, etc. I'm sure few people even consider mirror visibility, never mind make it a priority when buying a bike.
I used to be one of those who never based my purchase on the mirrors. However, I now know from experience that the degree of rearward visibility available while riding has a big influence on my overall riding enjoyment. Mirrors that provide excellent viewing ease greatly expand the pleasure of motorcycle riding. How important is mirror visibility? - I verified this again as an experienced rider, and firmly believe it to be vital.
From the results of my investigation, I can strongly recommend Honda's mirrors. And I also recommend that you take the time to evaluate Honda's motorcycles again from the perspective of their rearview mirrors. Doing so is easy. Just visit a dealership and sit on a bike. A dialog about the high performance Honda has to offer will soon begin.

PCX
Male, 30 years old
The original mirrors on this scooter have a fairly radical design that really fits the styling of the bodywork, give a good, clear view of what's behind, and really look like they were well-engineered by the maker. Needless to say, I've noticed no loss of visibility caused by mirror shaking or bodywork vibration. However, if the mirrors could somehow be lowered and more closely integrated with the bodywork while still maintaining their current visibility, I think they'd look even cooler and create more of a sense of oneness with the overall form.

SH mode
Male, 43 years old
When I was younger and just starting out on a motorcycle, I never paid much attention to the mirrors, and figured one should be enough. However, as I've gotten older and had more experience riding, I've become more aware of the importance of good mirrors, and even get a bit worried when other makes of mirrors are mounted. I've found that Honda's Genuine mirrors were designed with meticulous care, even if they accidentally bump into something. However, I think that the mounting and tightening method has become more complicated than in the past, so I'd be happy to see this problem solved somehow.

CB1100
Male, 55 years old
I used to ride a CB750F when I was young. At the time, I really liked the styling of its mirrors. I like this 1100 too because, more than just its air-cooled engine, overall it exudes a feeling of the Honda classics. It doesn't hurt that its mirrors are also similar to the 750F's in styling. I have no complaints about their viewing ease, and I like their styling as well. I'm reminded of my younger days whenever I polish those mirrors.
Female, 32 years old
A beautiful wine red color and the good feeling it exudes made me determined to buy a CB1100. Although many people say it has an old Honda look, I find its styling refreshing and delightful. Its mirrors also blend in well with the total design. If I polish not only the front surface of the mirrors, but also their entire bodies, I really like that I can see the surrounding scenery reflected in their shine. When I first switched from my earlier Super Sport, I was initially puzzled by the totally different positioning of the mirrors. But I soon got accustomed to using these easy-to-see mirrors, and now ride with complete confidence and peace of mind. I also enjoy seeing a bit of the sleeves of my dark-colored riding jacket reflected in the mirrors, though it might be better if the mirror height was lowered a bit.

CRF250L
Male, 58 years old
Since turning 50, I've been riding an off-road bike almost exclusively. That doesn't mean, however, that I've actually been doing any off-road riding. The reason is the bike's lightness and easy maneuverability, as well as its comfortable riding position for people of my generation who have less strength and slower reflexes. Off-road bikes are also the best in terms of their rearview mirror visibility. My CRF's mirrors were really well designed for an easy view of what's behind, which has definitely proved useful. With sports bikes, your rear view is often limited by your arms and shoulders. However, that sort of stress is totally eliminated with the CRF250L's mirrors.

CB1300SB
Male, 38 years old
Since I have the Super Bol d'Or version of the big CB, it comes equipped with quite a large frame-mounted front cowl, though its design is remarkably advanced compared to the Racer Replicas of a decade ago. Of course, its aerodynamics are excellent, and its rearview mirrors don't interfere at all with my riding. Their rearward range of visibility is as good as on a naked bike, so I never feel bothered in any way. Also, their design is beautifully integrated with the front cowl, and since they're positioned a bit farther away than normal, they're really easy to see.
-
FORZA
Male, 35 years old
Although I've been riding Honda scooters for many years now, I've found that the Forza's rearview mirrors are, in fact, very well designed. With my hands on the handlebars and facing the road ahead, I only have to glance to the side a bit to get a clear view of the conditions behind me. There's no need to turn my head a lot, so I feel a lot more comfortable. However, the height of the mirrors is almost exactly the same as the side mirrors of other cars on the road, which has given me a bit of a fright every now and then. If this problem could be eliminated, they'd be perfect. I really hope they come up with some sort of epoch-making idea to solve this.

VFR1200F
Male, 49 years old
For quite some time, I've been impressed by the Super Sports capabilities of the VFR. However, I've come to like the VFR1200F just as much as a touring bike. Before I actually bought it, I thought its mirrors were small and nicely styled. But when I finally had a chance to ride it, I was delighted to discover that I could see everything behind me in a wide field of view, even though the mirrors aren't particularly large in actual size. Since I have several motorcycles in my garage, I have to fold back the mirrors when I park there, as space is tight. When rotating the mirrors around, I can really feel that they're well-made and of the highest quality. Even the mirrors themselves are easy to adjust, so I have no complaints. They're all good.

CB500F
Male, 35 years old
I'm 176cm tall and ride a CB500F. Wherever I ride and whatever happens, the bike's superb Honda Genuine mirrors never shake or blur due to vibration, so I can't imagine replacing them with mirrors from other makers. However, if I could make a suggestion, I think it would be really helpful if Honda produced at least three different sizes of mirrors, so that riders could choose a set that best fits their body height. Also, a small portion of my rear view is blocked by the reflec tion of my arms, which I find distracting. If the mirrors could be raised a bit, I think I could have an easier view of conditions behind me.

GOLDWING
Male, 52 years old
Riding a monster like the Gold Wing, it's surprising how unobtrusive its mirrors are. I sometimes feel like I could split lanes and maneuver my way through the densest traffic. In other words, these mirrors are so well integrated into the Wing's front cowl that I hardly notice the bike's width. What's more, even wind protection was calculated into their design. When riding around town at normal speeds, I hardly ever feel any wind on my hands while holding the grips. And I'm also happy to report that I don't feel the cold so much in winter.

400X
Male, 26 years old
I chose this motorcycle with the idea of doing some long-distance touring on it. Although I haven't ridden it very much yet, I really like it a lot. I found that its mirrors were much easier to see with than those on a friend's bike. I wonder, is this related to their shape? I think these mirrors provide a very good view behind with just a quick glance. I usually don't pay much attention to mirrors, but this is something that I only really noticed for the first time when I rode other makes of motorcycles. I don't intend to ever replace the mirrors.
-
F6B
Male, 40 years old
I chose the F6B because I like how cool its styling looks with its top case mounted on back. Although I used to ride a bike with a V-twin engine until now, I'm really enjoying the tremendous power and acceleration produced by this bike's smooth and powerful engine. Even though its mirrors are essentially the same size as on the Gold Wing, a simple change in color makes them appear to be smaller and slimmer. I also really like that you can see with them as well as with a car's mirrors. And since replacing them with custom parts looks to be difficult, their excellent workmanship really eliminates any sense of stress.

CBR1000RR
Male, 35 years old
This is my third CBR1000RR, and I'm quite satisfied with the visibility offered by the mirrors, and their styling. One thing I especially like is how the turn indicators are integrated into the mirrors. I often take my CBR to a race circuit on track days, but even in such conditions, I don't like riding without the mirrors. The lack of mirrors makes me feel nervous, since it's hard to check who's coming up from behind judging from sound alone. I also sometimes take short touring trips from home to a café I frequent. The clear, wide view behind that these mirrors provide through town is definitely a plus.

CBR600RR
Male, 28 years old
I love sports bikes, and even the midsized ones feature full cowls, powerful engines and sharp handling. I chose the CBR600RR after I heard its engine is being used as the base for the World GP Moto2 class racers. Soon after buying it, I replaced the mirrors with some that had a carbon fiber finish and short stays that positioned them closer to the cowl. However, while I really liked the styling of these mirrors, the view out the back was so drastically narrowed that it made it impossible to see behind without contorting my body. As a result, it wasn't long before I went back to the original mirrors. The styling may have been good, but with such a drastically different range of visibility, my feeling of riding confidence was different as well. The aftermarket mirrors were cool, but they didn't help in any way, except to teach me how good the Genuine ones are.
