The T.M. DESIGNWORKS Case Saver is a black composite-machined case protection component designed for select Yamaha YFZ450R and YFZ450X applications. Its custom contours match the engine case shape for maximum support, while the open-face design helps reduce mud and dirt buildup. The case saver accepts one size larger sprocket than stock unless noted and is suitable for all types of riding.
Made from T.M. DESIGNWORKS' RMS (Return Memory System) plastic formula, this lightweight component absorbs impacts and uses the same durable material as the brand's rear chain guides. Hardware is included. The case saver is made in the USA and is used by championship-winning race teams worldwide.
Vehicle fitment includes the 2010 and 2011 Yamaha YFZ450X, 2018 Yamaha YFZ 450 X 4x2, and the 2011, 2015, 2016, 2017, 2018, 2019, and 2025 Yamaha YFZ450R. Distributor part number: 09501015. Manufacturer part number: YCS-YZR-BK. No case protector can save a case if the chain breaks under high throttle load; using high-quality sprockets and X-ring chains is recommended.
