Cometic 13-18 KTM RC390 Duke .020 Base Gasket

This package includes a Cometic base gasket specifically sized at .020 inch undersize. It's intended for use on 2013-2018 KTM RC390 Duke motorcycles.

When rebuilding or repairing the engine on your KTM RC390 Duke, a properly sized base gasket is crucial for sealing the cylinder to the crankcase. This gasket is manufactured by Cometic, a well-known name in engine sealing components. The .020 undersize specification means it's designed to be used when the mating surfaces of the cylinder and crankcase have been machined down, or if you're using a piston that requires this specific clearance. Using the correct gasket size ensures a proper seal, preventing leaks and maintaining optimal compression.
