Description
Stock pistons can’t handle the demands of high-performance riding—heat cycling, detonation, and sustained RPMs break them down. The Wössner Piston Kit for your CRF450R replaces worn or damaged pistons with OEM-grade engineering while reducing friction and noise for a noticeably smoother, more reliable engine. Complete with rings, pin, and clips, this is a straightforward refresh that restores your bike’s efficiency and reliability.
