RENNTECH // WANKEL ROTARY // KART RACING ENGINES

AIXRO XR50 ROTARY KART ENGINE

Developed as a response to increasing environmental regulations in Europe and North America, the XR50 puts out a fraction of the harmful emissions produced by conventional engines. Despite its low emissions, the Wankel 4 cycle rotary motor delivers all the power of a thoroughbred racing motor.

While the RENNTECH /Aixro XR50 delivers over 48 hp and 34 lb-ft of torque, the incredibly efficient design keeps the engine's weight to 32 lbs.; a power-to-weight ratio unmatched in kart racing.

Driving a kart powered by the XR50 engine is, istself, a unique experience. Besides the tremendous power to weight ratio of the motor, the XR50's eccentric shaft and rotor design (based on the original Wankel patents) virtually eliminate engine vibration, dramatically reducing material fatigue and part failures common to reciprocating engines. Along with other features engineered into the Aixro, this smoothness works to provide long engine life, delivering well over 100 racing hours between service.
