2025 Beta 450 RX

Features

• ENGINE MAPPING: The mapping has been updated with the latest settings that have been tested by the Beta race team. This along with traction control completes the electronic package of the RX model.
• FINAL RATIO / REAR AXLE: Rear sprocket has been replaced with a 51 tooth for a quicker "spin-up" of the power delivery. The rear axle diameter has been increased to 22 mm to reduce flex as well as provide better durability.
• FOOTPEGS: Enhanced grip performance while being less bulky so rider can maintain control at all times.
• HANDLEBAR MOUNTS: Xtrig FlexFix isoelastic bar mounts reduce rider fatigue and vibration. Also allows for flexibility in handlebar adjustment.
• SUB-FRAME & FILTER BOX: Subframe has been reinforced in key points that stiffen and strengthen it, maintaining lightness and ability to adsorb stresses. Access to the filter remains on the left side of the bike and is extremely easy and requires no tools to access.
• SUSPENSION: Closed cartridge 48 mm KYB front fork and the rear shock have been updated with valving for better overall performance.
• Updated front and rear suspension settings to help the fork stay up in the stroke while also providing better feel over the square chop.
• Larger battery for higher output and quicker starting.
• Different final ration with a 51T rear sprocket to help pull out of the corners harder.
• Smaller and lighter front brake caliper from Nissin, improved feel and modulation.
• Xtrig FlexFix handlebar mounts reduce vibration at the handlebar and raises the bar by 5mm overall.
• Footpegs provide a better bite over the previous version.
• Larger rear axle for more rigidity, now 22mm over last year’s 20mm.
• Updated engine mapping for 2025.
