    Superlite Countershaft Sprocket Wobble and Vibration

    I purchased the Superlite 14T countershaft sprocket, Superlite 34T rear sprocket and a DID 420 NZ3 chain. The Superlite front sprocket is quite a bit thinner than the stock sprocket. Even with the two sprocket bolts torqued to factory specs the countershaft sprocket has a ton of play as you can see in the video below. I can even hear the sprocket vibrating when taking off and coming to a stop.

    It's been so long since I changed sprockets on anything that I don't remember ever having this issue.

    How do I rectify this?

    looks ok to me, my sprocket does the same thing and I'm using PBI sprockets.

    Note to self, I won't buy either of those brands when I replace my sprockets

    The stock honda sprocket does the same thing. I think all my old dirt bikes were the same. I believe sportbikes were the only bikes where the front sprocket had no slop (its been a long time, can't remember).

    I've never had enough slop in a sprocket to the point where I was able to hear noticeable vibrations.

    My Grom front sprocket moves just as much what's shown in your video. All I can say is it seems fine so far. Sorry, not much comfort there. Hopefully more people can chime in!

    Just confirmed this myself. Bit surprised though. It's not as much as seen above but there's definitely play...

    It's not fine to me. I now have an annoying sound from the vibration of the sprocket when gaining speed and when slowing. I've never before experienced that on any motorcycle or quad.

    Interesting. I may contact Superlite. The little bit of play doesn't bother me. It's the new vibration sounds that I don't like.

    we've been riding these groms since 2014 or at least I have, so when you or newbies come here for advice either do your own research or go to the horses mouth which is Honda MC dealer and ask them direct.

    Most of the early grom owners know that this Front sprocket has a little slop but if you want it a little more snug than fab your own plate and holder and come back with a pic of your design and show proof your system is better than Honda engineers system.
