Designed with the freestyler in mind, the freestyle pump cone allows the engine to rev faster for the big tricks. Its small size lets a large volume of water move through the pump with less restriction than with the stock tailcone. This gives you more low end thrust for bigger air. No modification to stock pump required. Detailed instructions and all mounting hardware included. Fits all years Kawasaki SXR, 750SX, SXI, SXi-Pro, X2 and 650SX Models.
