Description
A top-end rebuild demands precision gaskets and seals—cheap alternatives lead to leaks, compression loss, and premature failure. The MOOSE RACING Top End Gasket Kit delivers OEM-quality seals at a fraction of dealer pricing, allowing you to restore your RMX 250 with confidence. Whether you’re replacing a worn piston or performing routine maintenance, this comprehensive kit includes everything needed for a proper rebuild without cutting corners.
Each gasket and seal is engineered for accurate fit and durability, with high-tech materials that withstand the demands of both trail riding and racing. If compression gains are your goal, the available high-compression variant uses thicker base gaskets to bump compression without expensive machine work—a smart alternative to full cylinder head modifications.
