Overview:
The Beta 125 RR is a result of a long development from the Beta R&D department aimed at filling a gap in the off-road market as a play bike, but also a serious race bike for the GNCC XC3 class & the NEPG Enduro classes.

Features: Six speed transmission, off-road light and meter package, adjustable power valve, broad power delivery, dual map switch selection, Sachs ZF forks with tool-less adjustability, hydraulic clutch, & pre-mix.
Radiator Shrouds
The new shrouds are narrower than before to give the rider more freedom of movement, especially when cornering. Designed to be sleed and also contribute to the revised, simple, and essential new look of the bike.
Power Valve
The power valve has been recalibrated to match the power delivery that the new crankshaft and crankcase has provided.
Rear Linkage
Unlinke others in the category, Beta RR models have a linkage system in the rear suspension for a more plush trail ride feel with the ability to react to sharp square-edged hits as well.
Electric start
An electric start for perfect start-up convenience whatever the situation (back-up kickstarter option available as an accessory)
Front Forks
The geometry of the oil passages around the fork piston has been modified to eliminate any air in the system to ensure impeccably smooth fork action throughout the entire travel. Resulting in improved rider comfort with more composed and controlled response even in rough terrain conditions.
