Beta RR 4T 480

Beta worked in close collaboration with the Enduro champions Brad Freeman and Steve Holcombe to develop a suite of new solutions regarding both the powertrain and the frame/suspension for the RR 2 Str and 4 Str models, to consolidate the already highly acclaimed characteristics of the previous generation.

As always, the guiding philosophy of the engineers at Rignano sull’Arno has been to not only increasing the performance of the brand’s bikes, but to also making this performance even more accessible.

Main competitors:

• Honda CRF450F
• Kawasaki KLX450
• KTM 450 EXC-F / 500 EXC-F
• Suzuki RMX450Z
• Yamaha WR450F

Engine

To take full advantage of the increased torque at low to medium engine speeds made available by the new exhaust header, 4 stroke models now feature dedicated new engine management maps which spread the power curve out more uniformly across the entire usable range of the engine, making the performance of even the biggest displacement Beta bikes completely accessible.

Clutch

Clutch with diaphragm springs - makes the clutch action smoother, more progressive and more controllable, significantly reducing rider’s fatigue.What’s more, three different spring preload settings are available, adjustable with a simple mechanical procedure.

Suspension

In the quest for an even sharper, purer rider feedback, Betamotor’s engineers have revised the internals of the front fork – a ZF component, as on the previous generation – of the 2023 model year of the RR family. This results in an improved rider comfort and in a more effective fork support throughout the initial excursion of the damper. Therefore, the bike remains composed and controllable even in rough terrain conditions.
