OVERVIEW

250 RX: Like the 350 version, this 2-stroke powered motocross model will appeal to all of those wanting a high-revving, lightweight 250 that can tear up berms with a distinctive sound that can only be heard from a Beta. The 250 RX also receives new engine cases along with the new cylinder, cylinder head, and exhaust. The 250 uses a single-spark head. Finally, a Beta Moto model that can run in many 250 classes.

Experienced riders love its versatility, seamlessly switching from fast tracks to technical Hard Enduro to singletrack thanks to an adaptable chassis and clicker settings that can be adjusted on the fly. Amateurs and weekend warriors appreciate the ease of use and confidence the bike delivers, keeping things comfortable even when the terrain gets demanding.

The 2-stroke range of motocross models also have been refined with updates to the following: Updated final gearing for the 250 to improve starts, New muffler that is stronger than the prior model, Dunlop MX 34 tires

By combining refined, high-revving power with a lightweight, confidence-inspiring chassis, the 250 RX is engineered to elevate the ride for everyone from seasoned competitors to weekend warriors.

MODEL HIGHLIGHTS

CHASSIS

HIGH-SPEED GEARING

The final drive ratio has been changed to a longer 14/51, widening the shifting points so the rider doesn't have to shift constantly, allowing each gear to pull longer and smoother through fast sections.

EXHAUST

UPGRADED 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.

FEATURES

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 rider's 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.
