Moose Offroad Hard-Parts – Engine Top Gasket Kit (ref. 810374MSE)
This Moose engine top gasket kit is designed for the refurbishment of the top end of 4-stroke motocross and supermoto machines. It includes everything essential to restore sealing during a cylinder head/piston disassembly: cylinder head gaskets, base gaskets, valve stem seals, O-rings, sealing rings, and necessary oil seals for refurbishment. The moulded rubber valve cover gasket is not included.
Ideal for running-in or servicing operations after disassembly, this kit provides a cost-effective solution to adjust compression without immediately resorting to high compression pistons or expensive cylinder head machining. It is particularly suitable for KTM SX-F 450 (2022), HUSQVARNA FC 450 (2022), and KTM SMR 450 (2021) models, as well as many 450 cc motocross/supermoto machines.
