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 – Full Range

The proven and tested suspension system and special components of the Beta racing version are confirmed:

Kayaba AOS 48mm closed cassette fork: anodized internals and material treatments minimize sliding friction, while adjustable compression and rebound damping allow each rider to find the perfect setting. Kayaba C46 RCU monoshock:

The KYB monoshock can be considered a benchmark in the racing context for its ability to absorb uneven terrain, the level of traction transmitted to the bike and the consistency of performance, even in particularly demanding use. Its hydraulic settings can be fully customized by adjusting the external compression (both high and low speeds) and rebound settings.

Quick-release front axle: this component, immediately recognizable by its red anodized aluminum release lever, is key to saving precious seconds in the race when you need to change a tire. Reinforced hand guards:

The hand guards are made of two-component material and not only give the bike a racing look, but are also particularly durable even in the most demanding off-road use.

Ergal alloy footrests: To ensure maximum control in all circumstances and without losing contact with the bike, the RR Race models are equipped with Ergal racing footrests with replaceable steel pins; these are narrower than in the past to facilitate foot movement, but better in terms of grip.

Rear sprocket with anodized aluminum core and steel teeth from ZF SPROCKETS:

top performance, lightness and strength - the perfect combination of all the features that every racing component must have. Special racing saddle: with anti-slip padding and document pocket for unrivaled grip, comfort and practicality.

Racing graphics: so that it never goes unnoticed on the racing field. Anodized black gear lever and rear brake pedal. Transmission oil filler cap, engine oil filler cap and oil filter cap made of red anodized aluminum.

Chain tensioners made of red Ergal alloy.
