The RR Race 250 2T has been designed to offer a greater torque and a consistently manageable response. A balanced displacement, perfect for those seeking performance and fluidity on all types of terrain.
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.
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.
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 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 racing footpegs with interchangeable steel pins. Narrower to facilitate foot movement, they offer superior grip for maximum control and feel with the bike.
Red anodised quick release front axle: essential for replacing the wheel in a matter of seconds and gaining precious seconds in the race.
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.
