The GYTR High Compression Piston Set was designed by Yamaha's very own engineering team. Countless hours of dyno work have led to the creation of this exclusive piston set. Utilizing proprietary data only known by Yamaha engineers, the GYTR High Compression Piston Set is for the serious racer looking for the ultimate performance! This kit includes piston rings, wrist pins, and clips.
Shallow valve pockets for increased compression (13.5:1 piston only; 15:1 when installed with the GYTR Race Cylinder Head Assembly, sold separately).
Under crown matching to keep consistent piston weights identical to stock weight to maintain perfect engine balance.
Designed to be used with additional GYTR accessories for the ultimate engine performance.
Requires use of minimum 112-octane racing fuel.
Notes: Highly recommended to be used in conjunction with GYTR Full Exhaust System by Dasa Racing and GYTR Race Cylinder Head Assembly. Requires the use of the Power Commander V by DynoJet Research and GYTR Race Connecting Rod Set, both sold separately. This accessory is restricted to closed-course competition use ONLY.
