RR 4T 350/390/430/480 MY 2022
There’s always room for improvement! Nobody understands this better than the official riders of the Betamotor team: Steve Holcombe, winner of the Enduro 2 World Championship, Enduro GP and Assoluti d’Italia titles, and Brad Freeman, winner of the Enduro 3 World Championship. Undisputed leaders of the 2020 season of the Enduro Championship, they are already hard at work for the 2021 edition. Another firm believer in this statement is Jonny Walker, who chose Beta as the team to take his extreme enduro performance to the next level in 2021. And Beta’s fans also know this, as they continue to choose its products and make the Tuscan brand one of the best sellers in its class.

Clutch with diaphragm springs
This solution makes the clutch action smoother, more progressive and more controllable, significantly reducing rider’s fatigue. Both engagement and disengagement have been improved, while the clutch is now capable of transmitting even more torque. What’s more, three different spring preload settings are available, adjustable with a simple mechanical procedure.
Electronic control unit
This unit has been improved to offer better “dry/wet” map management and to benefit of the engine brake effect more effectively, in order to let the rider make full use of the potential of the engine. The map selector button remains in its familiar position between the fuel tank and the headstock, where it is easily accessible but protected against accidental knocks bumps.
