2027 Beta 450 RXF 4-Stroke

2027 Beta 450 RXF 4-Stroke

More than just Bold New Graphics, the development of the 450 RXF model focuses primarily on the electronics and engine power delivery for the 2027 model year. Traction Control has been further refined to be more precise and useable. The two maps have been updated to make the most of the engine, and all controls are managed via a new integrated control panel. Rider can choose Dry or Wet and loamy track conditions with a push of a button. Like the new 250, the 450 RXF has added launch control and quick shift, combined with the overall 450 engine package, this system will allow riders to perform at a higher level.

Also new is the tapered 48mm - 44mm throttle body. This new component comes straight from the AMA Supercross team as well as the MXGP team in Europe. It provides increased air speed and volume to the motor which enhances the low-to-midrange power overall while providing a quicker throttle response across the board.

Features may include:

• 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.

• QS FAST SHIFT

Allows for lightning-fast upshifts without letting off the throttle or pulling the clutch, ensuring zero loss of momentum

• PERFORMANCE 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.

• Redesigned Control Panel

Redesigned Control Panel: The control panel houses the new LC and QS buttons alongside the proven 2-level Traction Control (TC) and dual-map switch. It integrates cleanly into a redesigned handlebar pad.

• NISSIN BRAKING SYSTEM

Equipped with a compact, lightweight, motocross-derived Nissin front brake setup that offers immense stopping power with excellent lever modulation.

• CHROMOLY STEEL FRAME

Celebrated for its natural flex, the chromoly frame absorbs harsh energy that aluminum frames transfer directly to the rider, providing immediate confidence through high-speed rollers

• SOFTER COMPOUND GRIPS

New, softer grips reduce rider fatigue and arm pump by absorbing trail vibration, allowing you to stay on the gas longer.

• FACTORY GRAPHICS

Eye-catching red and black livery conveys an aggressive and contemporary image to accompany the launch of the 250 4-stroke

• KYB SUSPENSION

The 48mm closed-cartridge front fork and 50mm rear shock offer industry-leading predictability, giving the rider maximum bottoming resistance on massive jumps while remaining plush over small acceleration bumps.

• HEAVY DUTY CHAIN GUIDE

Features a reinforced structure to withstand mud, rocks, and hard impacts from ruts and logs. A straighter, stronger guide ensures final drive stability, prevents thrown chains, and protects the swingarm.

• FLEXFIX HANDLEBAR MOUNTS

Handlebar risers utilize silent-block rubber mounts to isolate the rider's hands from engine vibration.

• DUNLOP GEOMAX MX 34 TIRES

Next-generation Dunlop tires significantly improve cornering bite while shedding unsprung weight, allowing the suspension to react faster to acceleration bumps and square-edge chop.
