Description
The Wiseco Piston Kit 68.50mm (+2.10mm oversized) is engineered for riders who demand more from their RM 250. This high-silicon aluminum forging delivers measurable gains in compression, top-end power, and durability—essential upgrades when you’re pushing a two-stroke to its limits. Whether you’re rebuilding after a failure or optimizing for race conditions, this complete kit eliminates guesswork with matched components designed to work in harmony.
Wiseco’s reduced-machining GP Series design tightens bore sealing while removing boost ports for a responsive, linear powerband. The E-coated crown and ring grooves resist wear from aggressive riding and high-heat cycles, keeping your engine reliable mile after mile.
