Description
The WISECO Piston Kit – 65.50 mm is engineered for Yamaha YFZ350 Banshee enthusiasts seeking maximum performance and durability. Crafted from high-silicon aluminum alloy, this forged piston ensures superior strength and dependability for both trail riding and high-performance racing applications. The innovative forging design and piston skirt geometry are optimized to deliver increased horsepower and torque, making it an ideal choice for serious riders and tuners looking to push their machines to the limit.
Each piston in this kit features advanced technology, including forged construction, high-quality rings, wrist pins, and circlips, all designed to withstand extreme conditions. The piston crown, ring grooves, and pin bore are E-coated to provide exceptional wear resistance and protection against micro-welding, galling, and detonation. This coating extends the service life of the piston, ensuring consistent performance over time. The design also incorporates maximum compression ratios and ultra-stiff strutted forgings, which contribute to a more efficient combustion process and more power output.
One of the key advantages of the WISECO GP Series pistons is the reduced external machining, which helps seal the bore more effectively and increases compression. Additionally, boost ports are removed to create a more predictable powerband and enhance top-end pull, giving racers and enthusiasts a competitive edge. For optimal performance, cylinder sleeves must be purchased separately. These pistons are designed for expert racers and tuners aiming to extend service intervals and achieve reliable, high-level performance from their Yamaha YFZ350 Banshee.
Whether you’re rebuilding for a race or upgrading for trail adventures, the WISECO Piston Kit – 65.50 mm provides the strength, precision, and power you need. Proper installation and tuning are recommended to fully realize the benefits of this high-performance component.
