The Radial Thumb Brake from Qnium is one of the most optimized thumb brakes on the market. As a rider you have a lot more feeling in your thumb than in your foot. The Qnium Radial Thumb Brake makes it easier to operate the rear brake in a very controlled way. This high-end thumb brake is very popular in the Moto3 class. A brake lever is not an option on these bikes, as Moto3 riders are required to use the clutch lever. When you mount the Rear Master from Qnium on your bike, you can continue to use your foot brake.

Drivers like Tony Arbolino and Dennis Foggia managed to win Grand Prix races with the revolutionary Qnium Thumb Brake. In 2019 Lorenzo Dalla Porta also used the Qnium’s Radial Thumb Brake, when he became World Champion Moto3.
