Designed to restore engine sealing without major modifications, the kit is 100% inspected and made in the USA.

Ideal for motocross cylinder preparation and maintenance, this kit offers improved tolerances compared to OEM and a contact surface designed to minimise leaks around the valve stems. It is particularly suitable for endurance-demanding models that are hindered by dust and heat from the tracks.
Indicative compatibility: notably Kawasaki KX 250 F (2012, 2016, 2018). Please check fitment on your model before installation.
