cylinder MotoForce Racing 70cc Derbi D50B0 MotoForce Racing 70 cc cast iron cylinder kit Derbi Euro 3 / Euro 4 for Derbi / Gilera / Aprilia motorbikes with Derbi Euro 3 / 4 engine - the perfect 70 cc cast iron cylinder for everyday use. If you want to replace your original cylinder with a more powerful and equally reliable model and not spend too much money on it, this Motoforce kit is a great choice. The MotoForce Racing 70cc cylinder is made of cast iron and features 5 transfer ports, a simple exhaust port and comes with a 2-ring piston with 47 mm diameter and a high compression cylinder head. In terms of performance, the MotoForce Racing cylinder delivers approx. 6 to 9 hp depending on the exhaust and is very torquey. Due to better torque, there is less need to use the high rpm range, which is easier on the engine and maintains engine reliability. And, of course, your starts will be much better - direct throttle response, great off-the-line acceleration, let's go! To ensure performance and reliability, we recommend combining the cylinder with a carburetor with at least 19 mm diameter, a reinforced clutch and a racing exhaust like the perfectly matching Stage6 Streetrace. In summary - the ideal 70cc cast iron cylinder for everyday use at an unbeatable price.
