Wiseco GP Series Piston Kit, 54.00 mm for GasGas, Honda and Yamaha (762M05400)

The Wiseco 762M05400 GP Series Piston Kit is engineered for high-rpm performance, dependable endurance, and improved engine efficiency in select GasGas, Honda, and Yamaha applications. This forged and machined piston is manufactured in the USA and designed to withstand demanding operating conditions while supporting consistent performance and long service life.
The piston features an electra-coated dome, ring groove, and wrist-pin bore for enhanced wear resistance and protection against micro-welding, galling, and detonation. GP Series pistons generally use less external machining, helping improve bore sealing and increase compression potential. This design is suited for riders and builders seeking a durable performance upgrade for high-output engines.
ArmorGlide® skirt coating helps reduce friction and operating noise while supporting increased horsepower potential. The coating works with the piston’s forged construction to promote smooth movement and reliable operation throughout the engine’s rpm range. The Wiseco part number 762M05400 is built for compatible 54.00 mm applications and should be matched to the engine manufacturer’s specifications before installation.
This complete piston kit includes the piston, piston ring or rings, wrist pin, and circlips for a convenient installation solution. Verify vehicle fitment, bore requirements, ring configuration, and clearance specifications before assembly. Professional installation and adherence to the engine builder’s recommended procedures are advised for optimal performance and durability.
