“Wanna play with us?” That’s the question Beta is asking riders as they launch the RX MY 2026 range — and the answer is a big yes for motocross fans.

Beta is stepping up its commitment to the MX world with an expanded and refreshed RX line-up for 2026. The brand introduces new 2-stroke models and significant updates to its 4-stroke machine, keeping one goal in mind: fun, performance, and control for every rider.

RX 450 4T MY 2026!

The RX 450 4T remains Beta’s flagship 4-stroke motocross bike and comes with important upgrades for 2026:

  • More Power, More Control: The 450cc engine has been completely revised. A new cylinder head, piston, intake boot, and exhaust system deliver stronger torque and smoother power across the entire rev range.

  • CFD-Optimized Airflow: A redesigned intake improves airflow, while a new counterbalancer reduces vibrations, making the ride more enjoyable and less fatiguing.

  • New Exhaust System: Developed with HGS, the longer header and new silencer reduce noise and refine throttle response.

  • Updated Engine Maps: Tailored to the new engine setup with improved starting and limiter strategies.

  • Traction Control & Mapping: The RX 450 4T features dual engine maps (dry/wet) and four traction control modes — all accessible via the handlebar button.

RX 250 2T & RX 350 2T – All-New 2-Stroke Weapons

Big changes come for the two-stroke range:

  • The RX 250 2T is an explosive new machine aimed at MX2 riders, designed to deliver quick response and powerful performance in a lightweight package.

  • The RX 350 2T is brand-new for 2026 and replaces the outgoing RX 300. It offers smooth power delivery with a focus on rideability for a wider range of riders.

  • New 2-stroke engines feature dedicated architecture, and the 350cc even uses a twin-spark cylinder head, boosting efficiency and control.

 Shared Upgrades Across the Range

  • Kayaba Suspension: 48mm front forks and 50mm rear shock with updated settings for both agility and stability.

  • Aluminum Subframe & Tool-Free Air Filter Access: Lightweight and easy to service.

  • Reinforced Radiators: Improved durability for the toughest tracks.

  • Nissin Brakes with Galfer Discs: Strong and precise braking power.

  • Lithium Battery & Lightweight Chain: Performance-focused components that save weight.

  • New Handlebar Silent Blocks: Reduce vibrations and raise the bar 5mm for better comfort and control.

The full RX MY 2026 range will be available starting June. Each bike also comes with a custom Beta stand and throttle cam options for the 4-stroke model to fine-tune throttle response.
