Dirt Bike Piston Kits

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!

  • Wiseco Piston Kit

    Wiseco Piston Kit

    Austin in WI

    Get the job done

    Quality is great. The piston came in a fabric bag inside the box to protect it. I used this to replace the factory vertex piston on my KTM. I will say this is a single ring and definitely a little lighter piston. Bike does vibrate slightly more not sure if it revea up any quicker like they say the single ring does. But overall great quality

    Racers choice

    This is a high quality piston. The ring end gaps were perfect out of the box. The increased service intervals over a stock piston is a bonus.

    Great replacement for OEM

    Went with the Prox because it is same as OEM for my CR125. Don't forget to order a wrist pin bearing, as this kit doesn't come with one.
