2026 BETA 450 RC

Beta USA is proud to announce an additional 2026 model to their impressive line-up, the 450 RC. The 2026 450 RC is a model that we have received many emails from customers asking us to build. Based from the success of the 450 RX Motocross model, the 450 RC shares the same proven and durable platform with additional feature added to make the bike a serious off-road race weapon.

The electric start, 5 speed engine provides the power delivery perfect for all-around use, designed for riders who race in the woods on the weekends and hit the moto track during the week, the 450 RC is really a do-all four stroke model. Equipped with an 18" rear wheel, larger fuel tank, handguards, Race model tank panels, formed plastic skid plate, and an o-ring chain to complete the package.

Features: Chro-Moly single tube frame with aluminum rear subframe, Nissin master cylinders and calipers, high-performance lightweight lithium battery, KYB 48mm closed cartridge front fork with a 50mm KYB rear shock with rising-rate linkage system, electric start, 18" rear wheel, ignition map switch and traction control to adjust engine power and provide less rear wheel slip, easy pull diaphragm clutch allows rider to adjust the lever feel and progression to their preference.

Features may include:

• Suspension

Closed cartridge 48mm KYB front fork and the rear shock have been updated with new valving for better overall performance

• Sub-frame & Filter Box

Subframe has been reinforced in key points that stiffen and strengthen it, maintaining lightness and ability to absorb stresses. Acceses to the filter remains on the left side of the bike and is extremely easy and requires no tools to access

• 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 22mm to reduce flex as well as provide better durability.

• Handlebar Mounts

Xtrig FlexFix isoelastic bar mounts reduce rider fatigue and vibration. Also allows for flexibility in handlebar adjustment

• 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 RC model.

• Footpegs

Enhanced grip performance while being less bulky so rider can maintain control at all times
