2002 Honda CR250 Chain & Sprockets

Installing a New set of Chain and Sprockets on the 2002 CR250 Build
Showing what to look for and when you need to change your own.

I felt like not enough attention was given to removing and installing the front sprocket, which is why I came to watch this video.

Thanks for the comment, the 2002 series was the first time I tried to film myself doing builds, I actually have another video in the 2004 build that might show you better and a pretty interesting tool I use as well. kzbin.info/www/bejne/eGe3dGeNftlrY80si=o9SiIv2cZGhHhARs Copy the link if it dose not actually link in the comments. Hopefully that will show more what you are looking for

Honestly… x-ring is the only way to go. There is no info anywhere that states otherwise. Say what you want… you are wrong. Sorry man 🌈🌈

kzbin.info/www/bejne/jJ-zipeZl8h0m5I here is a video from Fortnine, a Canadian retailer similar to Rocky mountain that has a few independent test on Lubrication that hopefully will help explain x-ring and o-ring chains and how they hold lubrication I hope this helps.

Do not blindly listen to Jeff above. If you have an older bike or Mx bike that never had an o-ring chain, it is imperative to check the chain width/clearance at the front sprocket, for rubbing against the case or just being too close for safety. O or X ring chains are generally a bit wider at the outer plate/rivet. I’d suggest borrowing a discarded piece of someone else’s o ring chain and check that first, before even buying an o ring chain. If it rubs or is too close, you will eventually damage the engine case. Now, depending on the bike, you MAY be able to buy special shims to move the sprocket away to create more clearance for the link plates and rivet heads. This will throw your chain line off as well, so keep that in mind.
