Wiseco GP Series Piston Kit, 58.00 mm for KTM (897M05800)

The WISECO 897M05800 GP Series Piston Kit is engineered for high-rpm performance, durability, and dependable operation in compatible KTM engines. This forged piston is designed to withstand demanding conditions while supporting consistent compression and long service life. Each piston is electra-coated on the dome, ring groove, and pin bore to improve wear resistance and help protect against micro-welding, galling, and detonation-related damage.

WISECO GP Series pistons generally use less exterior machining, helping the piston seal the cylinder bore more effectively for increased compression potential. An ArmorGlide® skirt coating reduces friction and operating noise, supporting improved efficiency and additional horsepower potential. The combination of forged construction, precision machining, and protective coatings makes this kit a reliable choice for performance-focused engine builds.

The WISECO 897M05800 kit includes the piston, piston ring or rings, wrist pin, and circlips required for installation. Engineered, forged, and machined in the USA, this piston kit is intended for compatible KTM applications using the specified 58.00 mm piston size. Confirm engine compatibility, clearance requirements, and installation specifications before assembly.
