  • Designed to allow you to upgrade the poorly manufactured TI valves to long-lasting stainless steel ones. By including valve springs engineered for the additional weight of stainless steel valves and more aggressive camshaft profiles, this kit will drastically improve the longevity and performance of your motorcycle. To help reduce the added reciprocating mass, we combine each kit with precision machined titanium retainers.
  • Each kit includes: 2 high-quality stainless steel intake valves, 2 high-rev valve springs and 2 titanium retainers.

Good Product

Comments On Feb 07, 2014:These are as good or better than stock ! I prefer the Titainium valves over stainless, and these have been great. 1000 + miles and clearance was still spot on.

2006 CRF 250

Comments On Jan 15, 2010:Working great so far, 4 months of riding and no shims. I was shimming the OEM valves every other ride and replacing the valves in less than 3 months.

Great

Comments On Dec 22, 2009:Good product. I only wish this came with the valve guide seals - you'll need to get those also if you're getting this kit.

These should come stock

Comments On Mar 01, 2009:I installed these valves in my CRF450 6 months after I bought the bike new. The stock valves needed shimming after every 2 races and ran out of adjustment very fast. Now after 6 months of use, these valves have not needed any shimming and the weight difference is not noticed at all. The increased durability far exceeds any anticipated loss of power, however; I never noticed any loss and unless you have money to burn on new titanium valves every 4-6 months and actually use every bit of power a 450 makes (be honest - I think maybe 4 racers in the U.S. can) these are a great investment! Also, my kit was complete, it included titanium retainers. The other reviewer most have lost the retainers that come in the kit or accidently threw them out because I found mine taped on the bottom of the box.
