After extensive testing with our racing drivers, the measures listed are a further development to improve the MEGA RS engine. Thanks to the reinforced crank drive and the modified piston shape, we were able to significantly increase the service life of our engine. By redesigning our cylinder, the engine now has more power and torque, with better modulation throughout the range.
