    Interested in the rear sprocket . . . staying stock on the front.

    The chain guide didn't need replacing. It was a Renthal chain and ran about $100.

    Get a good O-Ring or X-Ring chain (D.I.D., RK, etc.)

    I recently switched to 14/50 and it's pretty low with short tires. I haven't ridden dirt yet but I would expect it would do great, although IMHO it's a little too low for much street use. It's much better for wheelies though :evil

    Don't drop the front sprocket to 12 teeth. It is a known issue that it will eat your swingarm. I run 13 x 48.

    I also agree with Anne. The MT43 rear tire is great on the back.

    Yikes, I wish I had known. I used a 12T from the getgo and seldom checked my swingarm protector. Minimal wear....... But I only rode the bike for a little over 3 years, so probably not relevant. :huh


    The known issues are in descending order of impact (IMO):
    Kinking chain - lack of lube/maintenance
    Carrying heavy load and incorrect shock sag
    Incorrect chain adjustment
    Worn out chain

    I've read about 12T here:

    http://www.bigdogadventures.com/WR250R.htm

    "If you've put on a 12 tooth countershaft sprocket ????
    GET IT OFF !!!!
    This will only aggravated this "potential" problem----you'll be better off to work with the back sprocket for gearing changes.
    Also---I will never put even a stock 13 tooth on my bike from now on---I've got a 14 on it and will adjust my
    gearing to suit with different size rear sprockets."

    I ran a 12T for over a year (about 6k miles) and my swingarm protector is fine. Too much sag and a tight chain will chew it up no matter what size sprocket.
