350 RR Race 4-Stroke

Beta is rolling out the 2026 RR Race models earlier than usual, arriving ahead of the traditional October launch. This early release reflects Beta’s constant push to refine performance and detail—delivering race-focused enduro machines that are built to run at the front, while still staying true to Beta’s signature RideAbility.

For 2026, every 4-stroke RR Race receives updated engine mapping to improve power delivery across the entire rpm range. Regardless of displacement, the goal is the same: smoother response, stronger linear pull, and easier control of the available power from bottom to top. All Race models also feature a new rear brake hose routing system for improved fitment and function.

Proven KYB Suspension + Race Equipment

The RR Race models continue with Beta’s proven high-end suspension and race-ready hardware:

  • 48mm KYB AOS closed-cartridge fork with friction-reducing treatments and full compression/rebound adjustment

  • KYB 46mm shock with adjustable rebound and high/low-speed compression for consistent traction and control in rough terrain

  • Quick-release front axle with red anodized lever for faster wheel changes

  • Reinforced handguards with durable two-material construction

  • Machined alloy footpegs with interchangeable steel pins for stronger grip and better movement

  • ZF Sprockets rear sprocket with anodized aluminum core and steel teeth for strength and reduced weight

  • Dedicated race seat with non-slip cover and document pocket

  • Race graphics and finishing details including anodized black controls, red anodized oil caps, and red alloy chain tensioners

The result is a race-built package with sharper response, better control, and the durability needed for hard use—ready to line up and perform.
