Secondary transmission gear set TOP RACING 14/41 ratio for Minarelli

The Portuguese tuning specialists, Top Racing, are a symbol of high-quality scooter components. Thanks to advanced production techniques and more than 50 years of experience, many European brands entrust their tuning to Top Racing. The relatively simple installation of the Top Racing transmission is another reason to choose the Portuguese brand.
To increase performance and speed, you need more power and a longer gear. Since most vehicles are factory-fitted with a very short gear, you should install a longer gear to protect the engine from over-revving and make use of higher speeds.
As with the Malossi gear, the secondary transmission of Top Racing must be pressed together with the stock primary gears of the intermediate shaft. With a little skill, this is not too difficult. A local shop is usually ready to do this perfectly for a small fee. The ratio change differs depending on the original ratio and the model. Information in the extension table in Figure 2 provides
