Warning, potentially (really) dumb chain question ahead.

Greetings all, I'm a new owner of a 2018 GS (YEAH!). I've noticed that the chain rests on and makes contact with the hard rubber (?) cylinder attachment directly above the kick stand. I was expecting a free flow contactless path for the chain.

Question: Is the the design of the bike? Is this normal? If so, why does the chain run in contact with this part?

Thanks, and happy to be here!

yes its designed to maintain the chain tension,
most chain drive bikes have some sort on 'guide'
Other designs are strips of nylon-type material. etc.

@G0MYW , thanks I assumed it was supposed to be there. The amount of tension/friction on this part makes it a prime candidate for replacement in the not-to-distant future I suppose. I've seen guides on other bikes that seem less involved than this design.


@Bas310 thanks good to be here. I picked up a 2018 GS over the weekend with 1,000 miles and just getting to know the bike after an extended motorcycle hiatus.

Seems like a good fit for my needs out here in California wine country.

I need to get the clutch/levers dialed in better and would like to find a center stand if available. After getting to know the bike better, I'll re-evaluate and see what's next!

It's more of a tensioner than a guide. It keeps enough tension on the chain around the front sprocket while allowing sufficient slack on the rest of the chain to allow for the long suspension travel. It runs on bearings so it spins with the chain.
