If you need, I mean WHEN you need new valves for your CRF kibble white is the only way to go. My first set, 4 years old, are still in great shape. Just did my new bike with same kit. Best investment you can make for a CRF.

when replacing your oem parts these are a definite upgrade. they will outlast the oem valves by far, and make sure you get the spring set with these for an even better upgrade. i wasn't sorry and you won't be either.

Bought these for my 06 crf450r and 3 of the 4 were great but one would not let the shim seat in. Tried multiple new shims (hot cams). made it work but took some time.
