This is a set of genuine forged Vito's Performance SUPERSTOCK Yamaha Banshee pistons
This piston set includes rings, circlips, and wrist pins
Our line of Super Stock pistons for Banshees work to add power by simulating that the exhaust ports in your stock cylinder are timed differently which really means the same as hand ported with out the hassle.
The Super Stock is notched on the dome next to the exhaust port to theoretically raise the port, which will raise the rpm range of the engine and develop more mid to top end power.
Will add 8 horsepower to any unported Banshee!
No special machining is required - drop in an go!
Re-jetting is required since you will need more gas & fuel for all the Horsepower and Torque
