Wiseco GP Series Piston Kit 65.00mm Bore for Yamaha Banshee YFZ

Unleash the full potential of your Yamaha Banshee YFZ 350 with the Wiseco GP Series 65.00mm piston kit. Engineered for superior strength and performance, this high-performance piston kit is the ultimate upgrade for racers and serious enthusiasts seeking maximum power and reliability.

Description

Designed for the demanding conditions of both trail and racing, the Wiseco GP Series piston kit is meticulously forged from a high-silicon aluminum alloy. This advanced material ensures exceptional durability and dependability, making it a robust choice for your Yamaha Banshee YFZ 350 from 1987-2006. Each 65.00mm bore piston features an innovative forging design and piston skirt, optimized to deliver maximum horsepower and torque output. These high-tech designs are crafted to achieve maximum compression ratios, utilizing ultra-stiff strutted forgings and titanium nitride-coated rings. The result is a sustained increase in power and longevity, allowing you to push your machine harder and longer.

Every Wiseco piston in this kit undergoes an E-Coat process on the crown, ring grooves, and pin bore. This specialized coating provides maximum wear resistance, effectively protecting against micro-welding, galling, and detonation—critical factors for engine health and performance. The GP Series is characterized by less external machining, which aids in sealing the bore for enhanced compression. Additionally, boost ports are strategically removed to create a more predictable powerband and provide increased pull on the top end, giving you a competitive edge on any terrain.
