Description
When you’re pushing a CR80R to its limits, stock pistons become the weak link. The Wossner 8237DA replaces worn or damaged pistons with a precision-engineered component that delivers measurable gains in reliability and throttle response. Built with German engineering and FEA optimization, this complete kit handles the demands of both competitive racing and high-mileage trail riding.
Installation is straightforward—the kit includes everything needed (piston, rings, pin, clips) for a clean rebuild. The permanent skirt coating minimizes friction and piston rock, translating to smoother power delivery and reduced mechanical noise across the RPM range. If your CR80R has seen better days or you’re building a race-ready engine, this is the foundational upgrade that matters.
