MY26 Beta RX

Motocross, Redefined.
The 2026 Beta RX range marks a bold new era of Italian motocross innovation. From the all-new RX 350 2T — a world-first in motocross design — to the refined RX 250 2T and the race-bred RX 450 4T, Beta has engineered a line-up that blends explosive performance, precision handling, and championship-ready durability.

With upgraded frames, KYB suspension, Nissin brakes, and premium components across the range, every RX is built to compete at the highest level. Whether you’re chasing holeshots, pushing through motos, or lining up for MXGP-level performance, the MY26 RX range delivers motocross without compromise.

RX 250 2T – Lightweight. High-Revving. Relentless.

The RX 250 2T brings pure motocross aggression with a completely redesigned engine, calibrated power valve, and race-tuned internals. High-revving performance meets nimble handling, delivering a bike that rivals 250 four-strokes but with the unmistakable punch of a two-stroke. Explosive, precise, and built to dominate.

RX 350 2T – The Game Changer.

A world-first in motocross, the RX 350 2T redefines what a two-stroke can be. With its dual-spark head, torque-rich delivery, and purpose-built power valve system, it blends the agility of a two-stroke with the smooth, linear pull of a four-stroke. Manageable at low speeds yet brutally fast when opened up, the RX 350 2T is innovation on two wheels.

RX 450 4T – Factory Power, Straight From Italy.

The RX 450 4T returns for MY26 stronger than ever, with refinements inspired by MXGP and AMA Supercross competition. Featuring a new head, piston, intake, and HGS exhaust, this motor delivers explosive torque and higher revving power with reduced vibration for maximum control. With adjustable throttle pulleys, traction control, and reworked mapping, the RX 450 4T is the closest thing to a factory race bike you can buy.

Italian Precision. Race-Proven Power.
Every bike in the MY26 Beta RX range is built for serious motocross riders. From the innovative RX 350 2T to the powerhouse RX 450 4T, Beta delivers a line-up designed to push harder, ride faster, and win more. This is motocross, the Beta way.
