New 2027 Beta 300 RX

350 RX: New engine cases, bore and stroke, as well as a twin-plug head to ignite the special power only a big-bore 2-stroke can provide. The longer crankshaft, combined with the final gearing ratio of 14/47, provides a large amount of torque and overall horsepower that will turn some heads. This 350 motocrosser will thrive in many different track conditions. Clearly in a class of its own!

-A new piston for the 350 that saves weight as well as reduces friction, resulting in a 1.5 hp gain.

-Updated final gearing for the 250 to improve starts.

-New muffler that is stronger than the prior model

-Dunlop MX 34 tires

With more torque, increased horsepower, and a refined chassis setup, the 350 RX doesnt just competeit defines a new standard for what a big-bore two-stroke is capable of achieving.

Features may include:

• New Piston

A ground-up piston redesign optimizes weight and reduces inertia, delivering a 1.5 horsepower increase and instantaneous throttle response without sacrificing durability.

• UPGRADE MUFFLER

Both models feature updated internal silencer components to better withstand the stresses of intensive motocross use, maintaining optimal backpressure and avoiding power loss over long motos.

• NISSIN BRAKING SYSTEM

Equipped with a compact, lightweight, motocross-derived Nissin front brake setup that offers immense stopping power with excellent lever modulation.

• CHROMOLY STEEL FRAME

Celebrated for its natural flex, the chromoly frame absorbs harsh energy that aluminum frames transfer directly to the rider, providing immediate confidence through high-speed rollers.

• SOFTER COMPOUND GRIPS

New, softer grips reduce rider fatigue and arm pump by absorbing trail vibration, allowing you to stay on the gas longer.

• FACTORY GRAPHICS KIT

An eye-catching red and black livery conveys an aggressive and contemporary image to accompany the launch of the 250 4-stroke.

• HEAVY DUTY CHAIN GUIDE

Features a reinforced structure to withstand mud, rocks, and hard impacts from ruts and logs. A straighter, stronger guide ensures final drive stability, prevents thrown chains, and protects the swingarm.

• FLEXFIX HANDLEBAR MOUNTS

Handlebar risers utilize silent-block rubber mounts to isolate the riders hands from engine vibration.

• DUNLOP GEOMAX MX 34 TIRES

Next-generation Dunlop tires significantly improve cornering bite while shedding unsprung weight, allowing the suspension to react faster to acceleration bumps and square-edge chop.
