Drive chain? Sprocket? What are they?

You have ridden a bike, haven't you?

Of course! I was riding a bike almost every day!
Oh! A bike has a chain, too!

That's right!
Motorcycles have drive chain as well as bikes do!
* Some motorcycles use the drive belt or drive shaft instead of drive chain depending on the model.

The sprocket is the gear that engages with the chain!
The construction is very similar between a bike and a motorcycle.

I've fixed this as my bike's chain came off from the sprocket.

By the way, do you know why the bike chain came off?

Umm, I don't know! Just I realized that, it had been fine for a while, but it comes off easily since it came off for the first time!

Probably that's because drive chain got stretched and loose!

What?? Motorcycle chain gets stretched as well?

That's right.
That's why you need to check the slack of drive chain on a regular basis!
This is one of the items in the pre-ride inspection specified by Honda!
*The item "Inspecting the drive chain slack" is included in the one month inspection items.
For more details, refer to the owner's manual.

Doctor! If we keep riding the motorcycle with drive chain too tight, drive chain gets stretched sooner!
On the other hand, if drive chain is too loose, it doesn't engage with the sprocket properly, right?

You're right!
However, even it looks like keeping appropriate slack, which means neither too tight nor too loose, both drive chain and sprocket get worn out.
So, don't forget to have a periodic maintenance!

*The engine side sprocket also gets worn.

Benly

I understand now! Thank you !
I will make sure to have a pre-ride inspection and periodic maintenance!

Cub

If you find that drive chain is too tight or too loose at pre-ride inspection, go to a Honda Dealer and get it fixed right away!

Go to Honda Dealer and have a checkup!
Don't forget to replace it depending on the condition!
