Revolution Design Ultra Backplate for O.S .21 Engines

New from Germany’s Revolution Design comes this Ultra Backplate engineered to maximise fuel efficiency and enhance engine performance for OS .21 offroad engines.  A direct-fit upgrade for all O.S .21 offroad engines, including B2104, B2105, RNX, and Samurai models and their OEM versions, it is manufactured from high-quality 7075-T6 aluminium and PTFE hard-coated for durability and reduced friction, this precision-designed upgrade extends runtime by up to 30 seconds per tank.  The advanced internal design of the Ultra Backplate optimizes fuel dynamics by reducing flow resistance and improving fuel scavenging. When the exhaust port opens, the generated low pressure assists in drawing fuel more effectively through the crankcase, ensuring a smoother power delivery and increased efficiency, particularly in the mid-to-high RPM range.  At lower RPMs, the improved flow design maintains a more stable idle and smoother throttle response, contributing to an overall better engine feel and improved consistency.
