Bel-RayA(R) Works ThumperA(R) provides superior anti-wear and reduced cylinder and ring wear for longer bearing life. Its superior deposit control cleans deposits and controls sludge and varnish formation. This also keeps ring lands and grooves free of carbon build-up. The shear stability provides superior lubrication and film strength which minimizes friction for maximum power. Smooth power transfer prevents clutch grabbing for an easily controlled and efficient gear shifting and clutch operation.
