I've heard good things about them. My neighbor used to race his KTM and he swore those were the best and thats all he ran.
It depends how much a bike is rode also. I still have stock sprockets on my 98 & 99 XR100's in my dads garage. I rode them quite a bit and got them new. XR100 doesn't exactly have the power of bigger bikes though.

 

true...Im gonna order a set front and rear with their V-ring chain...didnt know if anyone else wanted in...might be able to swing a deal...:YEAH
