cp piston

04-05 Models have 0.25 less compression.  04-05 (239cc) 06-08 (249cc)

Each of these pistons incorporates an "X" style forging for addition strength, durability and weight reduction. Each piston is designed using sophisticated 3-D modeling software and manufactured with advanced 5-axis techniques making you piston the lightest and strongest piston on the market. Choose your compression.
