At the heart of the RS 125 is a sophisticated single-cylinder two-stroke, liquid-cooled engine, based on the same race-proven technology that has resulted in a continuous string of competition victories for Aprilia Racing. Able to reach triple digit speeds, the powerplant is packed with technical advancements including a crankcase reed valve intake, anti-vibration balancer shaft and an automatic fuel-oil mixing system. A robust 6-speed transmission delivers the power to the rear wheel with ratios designed to suit a variety of riding types. Bike also comes with the stock parts that the carbon fiber replaced and the Aprilia race wire harness. Upgrades: Carbon Fiber RH Engine Cover, Carbon Fiber Sprocket Cover, Carbon Fiber Chain Guard, and Carbon Fiber Rear Hugger. Give us a call at 713-222-2332.
