Fitment
Honda CRF250R 2004-2009. Verify exact model, year and configuration before ordering.
This is a well-made forged piston, you can definitely tell the quality of it over the stock cast piston, and the ring installation instructions were easy to understand. I added a DRD full exhaust system and a Hot Cams Stage 2 cam at the same time as replacing the piston so I don't know how much of the power increase is from the piston kit itself, but the bike definitely rips a lot more now like its a totally different bike! I am able to run 93 pump gas with it just fine.
