BETA RX 250 4T MY2027

BETA RX 250 4T MY2027 – new Beta motorcycle, supplied by Infinit d.o.o., the official Beta importer for Slovenia.

The suspension system relies on the KYB front forks and rear shock, already successfully used on the 450, but here equipped with a specific setting developed to adapt to the character and masses of the compact 250 powerplant. Contributing to completing the chassis package is a targeted choice on the wheel front as well: the rear rim features a narrower cross-section compared to the other models in the range, with the precise objective of reducing rotating masses, increasing the overall agility of the vehicle, and limiting power losses when putting the horsepower to the ground.

Launch control and quick shift: race-ready technology

The responsiveness of the new 250cc engine is supported by superior electronic management derived directly from the world of racing. The introduction of Launch Control, adjustable across five levels of intervention, optimises traction at the starting gate to maximise initial acceleration. The system works in synergy with the all-new Quick Shift, which allows higher gears to be engaged without closing the throttle or using the clutch, ensuring optimal gear-change smoothness and constant forward thrust.

Dual injection system

To maximise engine performance, a sophisticated dual injection system has been introduced. This system features two dedicated injectors: one positioned on the throttle body and one installed directly in the airbox sleeve. This configuration allows for optimal management of the air-fuel mixture, significantly improving response at low revs and ensuring constant power delivery at high revs.

Reconfigured dohc valvetrain

The all-new 250cc engine features a DOHC timing system with overhead camshafts and a chain positioned on the right-hand side rather than the left, driven by a gear linked to the water pump shaft. The timing system uses a Morse-type chain, equipped with a hydraulic tensioner, to ensure maximum reliability even at the high revs delivered by this model.

Electric starter and lithium battery

Reliable and secure starting on the first attempt in any weather or racing conditions, ensured by the standard electric starter powered by an ultra-lightweight lithium battery.

Racing crankshaft and connecting rod

The internal architecture of the engine reflects the project's pure racing DNA: the crankshaft features components made from dedicated forged steel and is supported by roller main bearings. The monobloc connecting rod utilises a bushing at the engine head to best withstand the specific high pressures, whilst the piston adopts a robust box-in-box structure.
