Pistons are constantly in motion, providing power to your dirt bike. But with the wear and tear of high RPMs, they can really take a beating and eventually wear out. Take good care of your bike by replacing worn out pistons, keeping your bike fresh. We stock a variety of excellent dirt bike pistons at the best prices. We carry many of the most popular dirt bike piston brands. Are you looking for Wiseco pistons? No problem. Vertex or Pro X? We’ve got those too!
If you just need a few replacement parts, we carry circlips, piston rings and wrist pins. Or we have complete dirt bike piston kits, from ProX to Wiseco. We even have high compression kits available for some bikes. (If you’d rather stick with the original stock components, take a look at our OEM parts.) Don’t let piston problems ruin your off-road fun. When you need a new dirt bike piston, nobody beats Rocky Mountain ATV/MC!

I have used these kits for years and have nothing but good results. They are reliable, easy to install, and add some good performance for the cost. I will always go this route as opposed to OEM.Read All Reviews

Definitely increased power low to mid and I would say slightly on top as well. The only complaint I have is I now have detonation when letting off the throttle. I run 92 octane pump gas and never had this problem before. I have attempted to add an octane booster to help but it has only helped slightly. I plan on running some AV100 to see if that solves the problem.Read All Reviews
