Electrical Systems for Greater Adventure

Electrical Systems for Greater Adventure

Not only has the basic performance as a motorcycle been thoroughly refined, the new model also features a touch panel TFT LCD multi-information display for infotainment, cornering lights, and other features. It offers a wider range of riding pleasure.

1.IMU (inertial sensor)

This sensor is capable of measuring yaw, pitch, and roll in six axes. By detecting the vehicle's attitude accurately and in real time, it enables more precise control of the quickshifter, DCT, HSTC (Honda Selectable Torque Control), wheelie control, electronic suspension, ABS, cornering lights, etc.

The Engineer Talks

-How does the IMU work?

“The IMU can detect bank angle, acceleration/deceleration, skidding, jumping, and other conditions. This allows us to activate traction control more precisely, and we can also detect jumping and increase suspension damping in preparation for landing. We can also control wheelies, which was not possible with the previous model.”

-I hear that the development has been quite a struggle.

“Actually, it is not so difficult to work on the development of each control system. The difficult part was that there is a lot more information coming from the IMU and all the controls are intertwined in a complex way; for example, if you change the meter program, the engine feeling could change .......”

-There doesn't seem to be a connection between the meter and fuel injection. ......

“You would think so. But despite that impression, all programs are intricately intertwined, and unexpected things often happen when something conflicts with some other instruction. It was a difficult development, as the more we tried our best in each section, the more problems we encountered. However, it was worth working hard for, as we were able to create a system with a high degree of perfection, in which many devices work in harmony and faithfully follow the rider's will during cornering, acceleration, and deceleration ....... I hope you will try it out in a variety of situations.”

Wheelie control is newly added to Honda Selectable Torque Control (HSTC). When the front and rear wheel speed sensors detect deceleration of the front wheel and acceleration of the rear wheel due to front wheel rise, the engine torque is controlled based on the vehicle pitch angle information from the IMU sensor.
In Level 3, front rise is controlled in all situations. Level 1 allows intentional front rise.


2.Cornering Light

The front face has been completely redesigned while retaining the identity of the previous Africa Twin models. Under the headlight is a cornering light that changes its illumination range in three stages depending on the cornering bank angle (Adventure Sports only). This improves visibility at night.

The Engineer Talks

-Until now, not so many bikes have been equipped with a cornering light. What is special about it?

“I have hardly ever had the chance to ride a motorcycle with a cornering light myself, but once you use it, you will never want to part with it. In the end, I tested it out while riding around the Takasu Proving Grounds in Hokkaido, but it was quite a challenge to get the maximum of three lamps to light up depending on the bank angle (laughs). I think this covers most of the riding situations.

3.Apple CarPlay

By connecting an iPhone via USB cable, you can use specific apps such as phone, music, navigation, and social networking to support comfortable touring.

The Engineer Talks

-I don't know if I'd make a phone call when I'm on a motorcycle.......

"My personal recommendation is to display a map on the meter. Even if you don't have to be navigated, just having a map within easy reach gives you a completely different sense of security.
It's a piece of equipment that takes you to go on a little adventure, to take a different road, or to dare to wander off the path!"

-That would also be helpful for people who are not confident about their sense of direction.

This allows you to get a sense of the approximate distance to your destination, which will give you a sense of comfort.
We also paid attention to the position of the display to ensure that it is neither too high nor too low so that you can always keep your eyes on the road ahead and get information without interfering with your immersion in the riding experience.

-I guess you could say it's an item that carries you into an adventure.

“Living in Japan, it may be difficult to take full advantage of the Africa Twin's potential and use it to blast through the desert. But that's not the only kind of "adventure" you can have. I hope you'll take advantage of the CRF1100L's electrical components and challenge yourself to create your own adventure!”
