Introducing the MY26 Beta RR 300 RACE 2T.
The RR Race models represent the race versions of Beta’s Enduro lineup, and is designed to deliver maximum performance while staying true to Beta’s hallmark philosophy of RideAbility. For MY26, there has been a series of changes, reflecting Betamotor’s commitment to innovation and its performance-based range.
Gearbox update:
The gearbox has been modified, by significantly lengthening the second gear. This has increased the smoothness when switching from second to third gear, with enhanced riding comfort and stability during and after the gear change. The result is a clear improvement in the bike’s race capabilities, where you can always identify the perfect gear to face any situation.
The main bearings on both the RR 250 & 300 RACE are larger and stronger.
The dual spark plug (on both the 250 2T and 300 2T) brings numerous benefits:
- It offers improved distribution of ignition points in the combustion chamber, with a consequent reduction in fuel wastage. This translates into greater carburation stability at all engine speeds, and more precise control of the engine.
- The engine’s range of use is further extended, with the delivery of greater torque and more power.
- The two spark plugs are managed with a separated electrical system. This means that if one of the spark plugs should foul, the engine will still be able to run, although with less efficiency, allowing the race or off-road session to be completed.

Components
The RR 300 RACE receives a new twin-spark head, improving the performance of the engine. The power delivery is more linear, and dispite the maximum power being increased, the tractability is significantly greater. It also creates a cleaner-burning ignition, alongside an improvement in fuel consumption.
Kayaba AOS 48mm closed cartridge forks ensure excellent operation under all usage conditions, being ultra reliable and easy to tune.
Kayaba (KYB) C46 Rear Shock: The KYB shock can be seen as a gold standard in the racing scene in terms of its ability to absorb the roughness of the terrain, the level of traction transferred to the vehicle and the consistency of performance even under particularly heavy use, and its hydraulic setting can be fully customised by adjusting the external compression (both high and low speed) and rebound settings.
Front Axle puller makes wheel changes quick and easy.
A new lighter, and higher-performing Nissin front brake caliper has been fitted to the RACE range, helping to maintain braking power, progressiveness and modulation.
The RR RACE range sees a new thicker rear axle for MY2025, up to 22mm in diameter. providing greater stiffness and torsional resistance.
Redesigned CNC alloy footpegs with steel pins are fitted to the RACE range, offfering greater rider control.
The engine map switch is now located with the bar pad, providing easier access.
