Race Series Engine Case Covers R&G's NEW Race Series Engine Case Covers have been specifically developed in collaboration with selected high level BSB race teams and crash tested in BSB level racing events to ensure they meet and exceed all required standards for case protection. The replaceable puck or slider is located on the impact face, giving the case not only more meat to grind through to further enhance the protection offered by a standard R&G Engine Case Cover but also offering an easy low-cost fix should you have a "minor" slide, crash or drop.
