Athena 19-22 Sherco SEF-R 450 Top End Gasket Kit

This Athena gasket kit uses laser-cut components, a detail that matters for sealing the critical areas of your Sherco SEF-R 450's top end. When you're rebuilding the top of your engine, having gaskets that fit perfectly and seal reliably is key to getting it running right. Athena engineers these kits in Italy, drawing on their internal knowledge to make sure each piece meets strict manufacturer standards.

The manufacturing process includes surface treatments designed to smooth out any minor imperfections and material stress-relieving steps.
