OVERVIEW

divider

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.

MODEL HIGHLIGHTS

LAUNCH
CONTROLS

Features 5 adjustable levels to manage torque delivery off the line. It maximizes traction immediately, preventing stalling or unwanted wheelies, perfect for occasional trips to the motocross track.

CHASSIS

PREMIUM SUSPENSION

The suspension system continues to rely on a KYB front fork and rear shock, already successfully used on the 450, but here fitted with a specific setup developed to suit the character and weight of the compact 250. Completing the chassis package is a carefully chosen set of wheels, with the rear wheel featuring a narrower profile than the other models in the range, with the aim of reducing rotating mass, increasing overall agility and minimising power loss during acceleration.
