Description
If you’re rebuilding a 2-stroke YFS200 Blaster engine, piston quality directly impacts your top-end reliability and power output. Wiseco’s high-silicone forged pistons deliver the thermal stability and durability needed for sustained high-RPM operation, whether you’re pushing hard on the track or trail. This complete kit eliminates guesswork—everything you need for a professional-grade top-end overhaul comes in one box.
The PK1089 is engineered specifically for Yamaha Blaster 1988-2006 models. Wiseco’s forging process reduces thermal expansion and creates pistons that maintain tighter tolerances under extreme heat, translating to better ring seal and consistent compression across the power band. Since this is a precision component, proper fitment with matching Wiseco rings is essential for reliability.
