Wiseco GP Series Piston Kit, 58.00 mm for Yamaha (846M05800)

Upgrade your Yamaha engine with the WISECO 846M05800 GP Series Piston Kit, engineered for endurance, high-rpm performance, and reliable operation under demanding conditions. This forged and machined piston is manufactured in the USA and designed to support consistent combustion performance, increased durability, and greater horsepower potential. The 58.00 mm piston size provides a precise fit for compatible Yamaha applications.
The piston dome, ring groove, and wrist pin bore feature Electra coating to improve wear resistance and help protect against micro-welding, galling, and detonation-related damage. GP Series pistons generally require less machining on the outside, helping promote a better bore seal and increased compression when properly installed with compatible engine components. Always verify application and fitment requirements before installation.
An ArmorGlide® skirt coating helps reduce friction and operating noise while supporting smoother piston movement and improved performance potential. The complete kit includes the piston, piston ring or rings, wrist pin, and circlips for a convenient installation solution. Built to WISECO standards, the 846M05800 piston kit is a dependable choice for Yamaha engines used in high-performance and high-rpm applications.
