BETA RX 350 2T MY27

2027 Beta RX 350 2T

The 2027 Beta RX 350 2T brings serious two-stroke performance to the motocross track, combining strong power, predictable handling and Beta’s signature RideAbility philosophy. Built for riders who want the performance of a large-capacity two-stroke without sacrificing control, the RX 350 2T delivers smooth, linear power with long gearing and consistent traction.

For MY27, Beta has introduced a newly developed lightweight piston designed specifically for the RX 350 2T. Reduced internal inertia helps create a faster, more responsive engine, while new PVD-treated piston rings reduce friction and improve efficiency and durability. Together, these updates deliver approximately 1.5 hp more power than the previous model configuration.

The 351.7cc liquid-cooled two-stroke engine features Beta’s BPV exhaust valve system, Keihin PWK 38 carburettor, reed induction, electric start and a five-speed transmission. Its combination of usable torque and responsive acceleration makes it ideal for riders looking for strong motocross performance with manageable power delivery.

The proven molybdenum steel double-cradle frame is paired with an aluminium subframe to provide a balanced combination of rigidity, stability and agility. Suspension is handled by a 48 mm KYB AOS closed-cartridge fork with adjustable compression and rebound, matched with a KYB 50 mm rear shock featuring adjustable rebound and high- and low-speed compression.

Stopping performance comes from Nissin braking components with Galfer wave discs, including a 260 mm front disc and 240 mm rear disc, delivering powerful and controllable braking across changing track conditions.

Additional MY27 updates include a reinforced chain guide, redesigned front sprocket guard, softer Beta-branded grips and an aggressive new red-and-black graphics package.
