The TPP-225RS engine was developed by Tillotson with extensive field testing by national and international kart racers over the past three years. It features a completely new crankcase design, which is heavily braced to allow for a larger piston size than other common four-stroke engines. The larger piston, with a diameter of 72 mm, provides excellent low-end torque and offers exceptional drivability, making it extremely easy to use for new drivers.
