The 2027 250 RXF is all-new from the ground up. The engine is a dual overhead cam with a piston design that came straight from F1 technology. Featuring electric start and dual-injector fuel injection, the power output is extremely competitive straight out of the box. This new power plant was designed and manufactured in Florence, Italy, in-house, ensuring the Italian passion is alive and well.

In terms of performance, the new engine ranks among the best in its class, thanks in part to sophisticated features: dual-injection system with injectors positioned on the 48mm – 44mm Tapered throttle body and inside the airbox. This configuration allows optimal management of the air-fuel mixture across the entire RPM range, improving response at low revs while ensuring strong, usable power delivery at high revs. The exhaust system developed by Beta engineers and HGS features a system that enhances performance while remaining lightweight and durable.

The 250 RXF benefits from a frame designed to meet the specific needs of a 250F size and feel. Compared to the central engine connection solution used on its big brother model, the design features side-mounted engine head mounts: an engineering choice that increases torsional stiffness while maintaining greater vertical flexibility. The result is a new balance between cornering precision and suspension performance, with significant benefits in traction and stability.

Completing the entire package is the tried-and-true suspension system, KYB front fork and rear shock, valved with specific settings developed to suit the lighter weight of the rider and bike. KYB suspension is the industry leader in Supercross and Motocross and was the only choice for the new 250 RXF.

With its all-new, high-output engine, precision-tuned chassis, and industry-leading suspension, the 2027 250 RXF isn't just built to compete—it's engineered to set a new benchmark for what a 250cc four-stroke can do.

Engine maps: all the RX models are equipped with two specific engine maps (wet and dry), while the 4- Stroke model has also four levels of Traction Control (on/off/active with hard map/active with soft map) to manage the vehicle’s significant power in all terrain conditions. The button to select the map and TC is located on the handlebar bumpers. All RX will be supplied with personalized kickstand. In addition, the 4Str has four different throttle pulleys to customize the accelerator’s response.

Handlebar silent block: Xtrig Flexfit bar mounts provide a comfortable grip on the handlebar for enhanced control and reduced vibration.

Lithium battery: lighter and a must for quick starts.

Chain: non o-ring, lighter and smoother.

Nissin braking system: with floating callipers and 260mm Galfer discs at the front and 240mm at the rear, for powerful and modular braking.

Kayaba suspensions: fork (48mm) and single shock (50mm) are specifically calibrated on the new range models, focusing on their rideability and stability when the pace rises. The resulting setting is enough to make any rider confident, from amateurs to professionals.

Aluminium rear sub-frame and dedicated filter box: aluminium gives the right level of stiffness to the structure. Light, yet has the rigidity to overcome the demands of motocross. Access to the filter remains on the left side of the bike, and is extremely easy and intuitive, as well as being tool free. The push button seat also removes without tools.

Frame: geometry remains unchanged, yet the frame now incorporates a cast-in brace to further strengthen the frame around the steering neck area. This increases the reliability and stiffness of the frame’s area most subject to stress.

Radiators: their bearing structure was strengthened to prevent any deformation that might affect their operation, even during heavy-duty use.

Graphics: a modern race look, simple yet bold, the final touch to the Italian RX range.

Exhaust system: the head-pipe has been redesigned to create a greater flow and to provide increasedpower. This new 4Str exhaust system is completed by a silencer, redesigned with HGS to contain the DB output, in line with the new racing standards

Engine: the 450cc engine development was focused on providing riders a significant performance increase compared to the previous model, offering a stronger torque curve that can be used under allconditions. This achievement was possible due to a new cylinder head with a performance-enhancingpiston, a new intake manifold and a different exhaust system. The head’s overhaul – developed through CFD analysis and many flow bench calibrations – includes an improved intake duct to enhance aircirculation inside the engine. The new manifold, following the flow line, has a longer internal horn toimprove the tuning of pressure waves, and thus increase their fill while intaking air. The piston includes new coatings to reduce friction and improve its performance. A newly designed counter balancer wasintroduced to contain vibrations and reduce rider fatigue.
