Kawasaki KLX125 Piston Set - Wiseco - 57.00 mm Bore, 11:1 CR - `02-`06. A forged Wiseco piston kit engineered to replace or upgrade the stock piston in KLX125 models, offering a complete rebuild package for performance-minded riders.

This Wiseco piston set is built from forged material for improved strength and long service life under higher loads compared to cast alternatives. The 57.00 mm bore and 11:1 compression ratio are matched to KLX125 `02-`06 requirements and the kit also covers common interchange applications such as Suzuki DRZ125 `02-`17 where applicable. Each kit ships complete with wrist pin, rings, and circlips so you have the parts needed for a correct installation. The forged construction helps resist wear from spirited riding and frequent use, while the included components simplify the rebuild process and reduce parts sourcing time.
