MAIN FEATURES

ENGINE

REDESIGNED ENGINE

The engine of the new RR Race 250 2T has been completely redesigned. The new crankshaft, now shared with the 300, has a reduced stroke (69.9 mm compared to the previous 72 mm) and an increased bore of 67.4 mm. This is supported by a redesigned cylinder with optimised transfers and a dedicated piston.

The new head, with a revised combustion chamber, uses a dual spark plug system: more combustion efficiency, full torque at all revs and stable carburetion even in the most difficult conditions. Thanks to better mass centralisation and a lower centre of gravity, the 250 is even more balanced and manoeuvrable, making every track pure fun.

Double spark plugs

The double spark plugs improve carburetion, torque and power, reducing fuel waste. The system also ensures continuous operation even if one spark plug burns out.

Kayaba AOS fork

Kayaba AOS closed cartridge fork, ø 48 mm has anodised internal parts and specific treatments that minimise friction. Compression and rebound adjustments allow you to always find the ideal setting.

Ergal footpegs

Ergal racing footpegs with interchangeable steel pins. Narrower to facilitate foot movement, they offer superior grip for maximum control and feel with the bike.

Front wheel axle

Red anodised quick release front axle: essential for replacing the wheel in a matter of seconds and gaining precious seconds in the race.

Racing design

An aggressive and unmistakable look: the dedicated livery enhances the Race character with bold lines and exclusive colours, recalling the factory soul of Beta and making you stand out on the track.

Chain tensioners in red Ergal alloy

Anodised Ergal chain tensioner: lightweight, stable and reliable, it guarantees constant chain tension and greater reliability in enduro competitions.

Kayaba C46 RCU Mono

Fully customisable monoshock with external compression (high and low speed) and rebound adjustments. A benchmark for consistent performance and traction even in the most demanding conditions.

HANDLEBAR MAP SWITCH

The map switch button located on the handlebar allows you to select two engine maps: Full Power, which offers all the power and responsiveness of the engine, and Soft, which softens the power delivery, making it more manageable on slippery surfaces or when greater traction is needed.

Power valve

Beta’s 2-stroke engines are equipped with an external exhaust valve adjustment that allows the rider to customise the engine’s power delivery to suit their preferences by simply turning a screw.

Updated gearbox

The gearbox of the RR Race 250 2-stroke has been modified, with a significant lengthening of second gear. This modification generates greater fluidity in the transition between second and third gear, improving riding comfort and vehicle stability during and after gear changes. The result is a significant improvement for use in competition, where you can always find the perfect gear ratio to tackle any situation.
