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.
Lineup:
Main competitors:
Engine
Beta RR 250 engine is very similar in design to its competitors, has the same piston stroke and cylinder bore as KTM, Husqvarna, GasGas.
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.
