ENGINE RR 4T RACE 390 MY 2026

RR Race 4Str

4-stroke engines received new maps with respect to the previous Model Year, to improve their delivery along the entire range. Whatever the displacement, Beta engineers optimized their linearity and usability of the propellers, to better manage the power available, at any speed, even on complex terrains.

Racing Components – Entire Range

The tried and tested suspension package and the special components of Beta’s race-ready version are confirmed:

• ø 48 mm Kayaba AOS close cartridge fork: anodised internal parts and the treatments administered to the materials minimise sliding friction, while adjustable compression and rebound damping let each rider find the perfect customisation of the setting.
• Kayaba C46 RCU Monoshock: the KYB Monoshock can be considered a benchmark in the racing context for its capacity to absorb the roughness of the terrain, the level of traction transferred to the vehicle, and the consistency of performance, even in particularly heavy use. Its hydraulic setting can be fully customised by adjusting the external compression (both high and low speed) and rebound settings.
• Quick release front axle: immediately recognisable by the red anodised alloy release lever, this component is crucial for saving precious seconds in a race when you need to change a tyre.
• Reinforced handguards: the handguards feature a two-component material mould, and not only give the bike a racing look but also make them especially hard-wearing in even the roughest off-road use.
• Ergal alloy footpegs: to ensure maximum control at all times and no loss of contact with the bike, the RR Race models are fitted with Ergal racing footpegs with steel pins which are interchangeable; these are narrower than in the past to facilitate movement of feet, but better in terms of grip.
• Rear sprocket with anodised aluminium core and steel toothing by ZF SPROCKETS: top-class performance, lightness and strength – the perfect mix of all the attributes any racing component must have.
• Dedicated race seat: with non-slip upholstery and document holder pocket for unparalleled grip, comfort and practicality.
• Racing graphics: to never go unnoticed on the race field.
• Anodised black gear lever and rear brake pedal.
• Gearbox oil filler cap, engine oil filler cap and oil filter cap anodised red aluminium.
• Chain tensioners in red Ergal alloy.
