Description
The Wiseco Piston Kit PK1390 is engineered for 2-stroke racers who demand peak performance without compromise. A worn or stock piston limits your YZ125’s power delivery and throttle response—this kit restores and exceeds OEM capability through precision engineering and advanced materials.
