6MIK has presented their new Optima ‘Booster’, a rear cover for Team Orion CRF engines. This optional rear crankcase cover features two internal channels increasing engine efficiency by optimally feeding the ports. In addition, thanks to a mixture less impacted by the movement of the conrod, the engine offers improved idle stability, fuel mileage (+ 30 seconds Refuel) and overall engine performance (+ 20 % Torque).
