W836M05800 - W836M05800 - Wiseco GP Series Piston Kit - KTM SX125 2001-06, Suzuki RM125 2004-10

Features: Endurance and high rpm. Each piston is electra-coated on the dome, ring groove, and pin bore, for maximum wear resistance and protection from micro-welding, galling and detonation. GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression. ArmorGlide® skirt coating reduces friction and noise for more horsepower potential. Kit includes piston, ring(s), wrist pin and circlips. Engineered, forged, and machined in the USA. Does not have an intake window. Pinned on centerline. Fits Nikasil bore cylinder and SCEM (Suzuki Composite Electrochemical Material) cylinder. Sleeving or replating is required..
