The WISECO piston is intended for replacement or engine preparation when a machined and uniform part is desired, compatible with the specified bore tolerances. The "A" oversize corresponds to a slightly increased diameter to compensate for wear during a standard re-bore. Installed with the supplied rings, it allows for a clean and controlled fit.
Common applications: ideal for SUZUKI RM-Z 250 (2007, 2008, 2009) and other motocross models compatible with Ø 76.95 mm. Please verify compatibility with your displacement and machining specifications before installation.
