Beta announced details of their 2022 enduro range today. As expected, there are engine changes to the two-strokes and clutch changes across all models – in line with the updates made to the ’22 XTrainer earlier. Plus they’re all fire engine red for the new model year!
There’s a big UK connection with Beta thanks to the recent multiple world championship wins by Beta works team riders Steve Holcombe and Brad Freeeman, and the signing of extreme star Jonny Walker to the team for this year. And there’s no end of love for the no-nonsense RR two-strokes among UK racers.
For all models:
Suspension
 The rear mono-shock gains new compression damping settings with independent high and low speed damping rates. This prevents the two parameters from influencing each other and limiting the customization of the setting. The settings available for the fork have been revised to improve rideability and precision during extreme use. The fork tubes are now different in colour, thanks to the new anodising process which improves the surface hardness and corrosion-resistance of the component.
Graphics
All models now feature a new all-red colour scheme. Combined with the new graphics, which perfectly match the shape and componentry of the bike, the new style gives the bike a very sleek, race-bred look.
RR 300 two-stroke
Engine
As with the XTrainer, the engine has been substantially revised, with a larger bore cylinder, a new piston and a new power valve.
Crankshaft
A new shorter-throw crankshaft, for a shorter piston stroke than the previous model.
Cylinder head
The head is also completely new, and has been redesigned in consideration of the other new components and the new iridium spark plug.
Silencer
The smaller diameter silencer improves the top-end performance and tractability of the engine.
Clutch with diaphragm springs
The RR 300 gains a new clutch, with smoother and lighter action, more effective engagement and increased transmissible torque. This clutch also features mechanically adjustable spring preload, offering a choice of three settings with a specific adjuster ring.
RR 250 two-stroke
Clutch with diaphragm springs
Same as with the RR300.
RR 125 two-stroke
Cylinder head and power valve
Redesigned to maximise torque at mid-to-high engine speeds – the range in which the 1/8th litre Betamotor power unit truly shines.
RR four-strokes
Electronic control unit
The most significant new feature on all four-stroke models is the new and more sophisticated ECU. This should give a better wet/dry engine mapping management and take advantage of the engine brake effect more effectively, 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 which could inadvertently change the setting or break the button itself.
Transmission
A lighter new primary transmission has been introduced across the entire four-stroke range, while these models are also equipped with the new clutch with diaphragm spring with three user-settable spring preload levels, with more progressive and smoother control action and, as already mentioned, increased transmissible torque.
Â
And that’s it. The big news there is the new bore and stroke in the 300 motor and the new clutches. As ever, a strong offer from Beta in terms of tech and looks. The new models should be available from June.
