The WISECO Piston Kit is designed for Yamaha YFZ350 Banshee applications and features a 65.50 mm piston size. Manufacturer part number 795M06550. This Racer's Choice GP Series piston kit is forged from high-silicon aluminum alloy for strength and dependability in trail and racing applications.
The kit features a forged piston, rings, wrist pin, and circlips. Its forging design and piston skirt are engineered to support increased horsepower and torque, while the high-compression design, ultra-stiff strutted forging, and titanium nitride-coated rings help provide sustained power. The piston crown, ring grooves, and pin bore are E-Coated for wear resistance and protection from micro-welding, galling, and detonation.
GP Series components generally have less machining on the outside to help seal the bore for increased compression. Boost ports are removed for a more predictable powerband and increased pull on the top end. Cylinder sleeves must be purchased separately. Racer's Choice pistons are intended for expert racers and tuners only, and service intervals may be increased compared with conventional WISECO pistons.
Fitment includes 1988, 1994, 1995, 1996, 1997, 1999, 2000, 2001, 2002, and 2006 Yamaha YFZ350 Banshee models.
