Primary Gears Malossi 13/44 Yamaha Aerox / Bw's

Malossi HTQ Primary gear 13/44 Minarelli / Aerox Malossi primary gear, 13/44 Minarelli horizontal and vertical. Suitable for all scooters with Minarelli engine (Aerox, Neos, Jog, Booster, Nitro, F12, F15 etc...) A longer gear ratio shifts engine power to where it’s needed most, assuming the engine delivers the extra output. On heavily tuned engines, extended gearing offers a clear advantage. However, such gearing is not suitable for stock setups. Installation Note:The large gear must be pressed onto the original intermediate shaft. This requires special tools and/or a hydraulic press. We can offer you gearboxes from Stage6 that do not need to be pressed!
