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!

    Great product which performs perfectly.

    When it was time to put a new piston in my 250 EXC, I didn't even consider any other brands. All my riding buddies use Vertex and all have performed flawlessly. I'll always use Vertex.

  • Cylinder Works Standard Bore High Compression Replacement Vertex Piston Kit

    Cylinder Works Standard Bore High Compression Replacement Vertex Piston Kit

    Greg in UT

    Excellent piston!

    I was looking to replace my stock piston during a top end rebuild. I decided to go with the Vertex piston as it had good reviews, and I wanted to go with a high compression piston. This piston checked all of the boxes for me. It is a great part. I've put about 15 hours on the piston, and the engine pulls incredibly well. It went in very easy during install as well. If you're looking for a high compression piston replacement, this is the one to get!
