What is the stock chain and sprocket size for a 2002 yz 250?

Any recomendations on what kind of chain/sprocket to get?

if you go to rockymountainatv.com and search for chain, it will ask you to type in the year, make and model, and then it shows you all the specs for your bike :lame:

I would look for you myself, but I'm at work right now and it blocks me :bonk:

Should be close to 14/48 or 14/49, with a 520 chain @ 114 links..

I said close, no promises that is what you need :lame:

pretty sure they come stock at 14/50 gearing, 520 chain with 114 links.

I just did mine, but its a '93 with 14/49 gearing, 520 chain at 116 links.

I got a DID professional o-ring. Still waiting to get the motion pro press tool to get the front plate to go on.

Good luck!

That sounds kinda odd. 2 more links for 1 less tooth...

My YZ/F's come with 13/49 and 114 links, so I would say just get a 116 but get a chain breaker. I always buy 120 links anyways and just break them.

Agreed.. :lame: I also do the same and usually run one link long.. This brings the back wheel further on the swingarm and extends the wheel base.. Stability at speed :lol:

To answer the question about more teeth, less chain.. I believe it has to do with swingarm length... :bonk:

I thought the same thing.....i would have to agree with bikedude about swingarm length being the reason. I went with the amount of links that was stock, couldn't believe how much the old chain stretched out. When this comes around again I will definitely go with a 120 link and break it at desired length, I really could have used a link or 2 more this go around.

My bad, I read it again. I first skimmed it and thought it said 03, not 93. That could make the difference!v:thumbsup:
