Primary Gears Malossi 14/42 with bearing Yamaha Aerox

Description Malossi MHR Primary Transmission 14/42 w/ additional bearing for MBK Nitro / Aerox.The transmission has a gear ratio of 14/42 for higher top speed, at the same time acceleration will not be affected. This gear ratio is ideally suited and often used in 70cc racing engines. As tuned engines have a tendency to vibrate, Malossi added extra ("third") support to the primary drive shaft. An additional third bearing in the transmission cover provides extra support and stability. Minor modifications are necessary to accommodate this transmission, but we can assure you that it's well worth it! It takes about 15 minutes to do this, detailed instructions are given in the manual.Details: primary transmission w/ straight teeth gear ratio: 14/42 press-fitting Questions about the product

Notes and Safety Scooter gearboxThe transmission of scooters and some mopeds is located in a case behind the clutch and torque driver and has the function of reducing rpm and ultimately driving the wheel axle.The transmission of a scooter has a direct influence on top speed. If the engine develops enough power and torque at low rpm, you can choose a longer gear ratio to achieve a higher top speed without any noticeable loss in acceleration.Please note: if you don't have a press, better choose pre-assembled gears!
