MOOSE RACING Top End Gasket Kit - CR250R 810252

When you're rebuilding a CR250R top end, gasket failure isn't an option. This Moose Racing kit eliminates the guesswork by delivering every seal, O-ring, and gasket you need in one package—all manufactured to precise tolerances and backed by proven reliability. Whether you're doing routine maintenance or a full piston replacement, you get OEM-quality components at a fraction of OEM pricing.

The high-compression variant offers a smart alternative to expensive cylinder head work: use .012" thick base gaskets to measurably raise compression without investing in new pistons or machine shop costs. Every component is engineered for accurate fit and durability, so you can rebuild with confidence and get back to racing.
