Other Specifications

Modificationscomparedtopreviousmodel	REV-3 250/270Cc – 2008 Technical Modifications New fork settings. Optimisation of the oil-flow has made the forks more sensitive in absorbing the bumps. New shockabsorber settings. More stable performance over time, combined with greater reliability. New Keihin PWK ø 28 mm carburettor: more immediate and lively response at the bottom end, together with a marked improvement in power and acceleration in the middle-to-upper range. New filter box to optimise the fit with the new Keihin carburettor: improved airflow thanks to a larger diameter sleeve. New crankcase. New design in the area of the connection between barrel and crankcase has reduced crank chamber volume with a nett increase in smoothness at low revs. New cylinder head design (on the 250 and the 270cc) ensures more regular carburation when shutting the throttle and provides greater engine torque. New single-chamber silencer (270cc only): smooths out the power delivery at low engine speeds making it even more linear, and provides a noticeable increase in power and acceleration at the top end. New main bearings: these ensure greater smoothness and reliability. New crankshaft oilseal: the reduction in friction has given the engine a cleaner response to the throttle. Euro3 homologation. New colour-scheme: a brand-new mix of white and fluorescent red.

About Beta

Country of Origin: Italy

Founder: Giuseppe Bianchi & Arrigo Tosi (Betamotor S.p.A.)

Best Known For: Trials and enduro dominance; RR/RS enduros and Evo trials line

Company History

Betamotor began in 1905 building bicycles in Florence and evolved into one of the world’s premier off-road motorcycle makers. The company’s DNA is balance and traction—first in observed trials, where featherweight control and throttle finesse matter, and later in enduro, where day-long reliability meets special-stage speed. Beta’s modern RR/RS enduros are renowned for chassis that communicate clearly, engines with tractable midrange, and suspension valving that works out of the crate for real riders, not just pros. The Evo trials line continues to win at the highest levels, feeding lessons about weight distribution and clutch feel back into the enduro range. Unlike some rivals, Beta embraces rider-scale adjustability—map switches, power valve tweaks, and ergonomic options that let owners tailor bikes without a race truck. Historically, Beta personifies Italian craftsmanship aimed at dirt: elegant castings, tidy looms, and field-friendly service. Club racers and trail riders praise how Betas turn fatigue into flow; the bikes reward precise inputs yet forgive mistakes. In a category where specs are loud, Beta’s quiet confidence—how the bike feels between trees—has built a fiercely loyal following.
