Wiseco Piston Kit - 68.50 Mm For Yamaha It/Triz 250 - High-Performance Forged Aluminum

The WISECO Piston Kit - 68.50 mm is engineered specifically for Yamaha IT and TriZ 250 models, delivering exceptional strength and durability for both trail riding and racing applications. Crafted from high-silicon aluminum alloy, this forged piston provides maximum dependability and long-lasting performance, making it an ideal choice for enthusiasts seeking increased horsepower and reliable operation.

Designed with innovative forging techniques and a meticulously crafted piston skirt, this piston maximizes horsepower and torque output while maintaining structural integrity. The kit includes forged pistons, rings, wrist pins, and circlips, all engineered to work seamlessly together. The advanced piston design features ultra-stiff strutted forgings and titanium nitride-coated rings, which contribute to higher compression ratios and enhanced sealing. These features help optimize power delivery and improve engine efficiency across a range of riding conditions.

Each piston is E-coated on the crown, ring grooves, and pin bore, providing excellent wear resistance and protecting against micro-welding, galling, and detonation. This protective coating extends the service life of the components, especially in high-performance scenarios. The GP Series pistons are designed with less external machining, which aids in sealing the bore for increased compression and more efficient combustion. Additionally, boost ports are removed to produce a more predictable powerband and a stronger pull on the top end, making it suitable for competitive racing environments.

Note that cylinder sleeves must be purchased separately. These pistons are intended for expert racers and tuners looking to maximize engine performance and are suitable for those who perform regular service intervals. Whether you're upgrading your Yamaha IT or TriZ 250 for trail adventures or competitive racing, the WISECO Piston Kit 68.50 mm offers the strength, reliability, and performance enhancements necessary to achieve your riding goals.
