BETA RR 125 LC 2021

2021 BETA RR 125 LC

Beta has revamped their RR 125 LC enduro-trail bike. And boy it looks like a ripper...

Italian enduro specialists Beta have revamped their RR 125 LC street-enduro for 2021 – new frame, new bodywork and a Euro 5 pleasing motor. It looks like it could be a great trail bike and should be a wonder in the green lanes.

Here’s what to know:


Okay, it’s a humble 125cc four-stroke, so it’s not going to rip your arms off. But it is ultra-modern. It’s a completely new motor from Minarelli, upgraded to Euro 5 spec. It has electronic fuel injection, variable valve timing and a slipper clutch. The cooling system has been revised for – well, better cooling. The airbox has been reshaped (from the 2020 model) to improve breathing and accessibility of the filter.


The frame has revised geometry for improved handling. The new all-red bodywork replicates that of the Beta competition enduros – it looks super-sharp. Headlight and taillight are now LED. There’s a CBS combined brake system (we could do with more detail on that). Suspension features 41mm USD forks and an aluminium swingarm. A new ‘Alu’ exhaust and a new (presumably better) sidestand.

Dry weight is a wonderful 98kg but the seat-height is a competition spec 920mm – which you kind of have to expect given 265 and 270mm of suspension travel. Fuel capacity is 7.5 litres, which given a very frugal fuel consumption of two litres per 100km gives a theoretical range of 375km.

RUST says:

We need to get rid of our UK prejudice against small capacity machines. Within the context of green lanes this bike could be a weapon. By that we mean it’s small, quiet and light and should have excellent handling given Beta’s pedigree. And given we should not be tearing up green lanes like we’re on a special test those three qualities combined with a sensible motor will make it a great match for older and younger trail riders alike. The appeal is similar to that of the Honda CRF250/300, only this bike is 98kg not 142kg and with a serious off-road spec…


UK delivery is April/May, price £4745 (price held from 2020)
