Genuine YAMAHA Gaskets and Seals

I use nothing but Genuine YAMAHA Seals in every engine I build. To me the bottom end is the heart of the engine and I like to build the bottom end with the best possible parts available and then not have to worry about going back into it for a LONG time. I couldn't find any Factory YAMAHA RD250/340/400 or TZ250/350A-G bottom end seal kits so I made my own. I’ve included what I put in every bottom end I build, nothing extra that’s gonna sit on a shelf collecting dust and all Factory Yamaha parts.

RD250 Racing Pistons


Finally a true Hi-Performance piston for the Yamaha RD250’s and RD250LC’s. After months of work with Wossner and a group of top notch two-stroke men from around the world we came up with one great performance piston for the RD250’s and RD250LC’s. Driven by the needs of RD250 and RD250LC racers around the world we took the necessary time to give this piston every possible advantage we could think of.
