Could be better....
Overall a great product. A much needed upgrade over O.E. spacers. The o-rings really do their job.
The only flaw in this particular fit (2000 RM250) is you have to re-use the right side O.E. spacer along with the Pivot Works kit. If the original RH side is trashed, you will need to visit the dealer for a replacement.
I put this kit into a 2005 RM250 and did not need to reuse any of the original spacers.
