Beta RX Motocross Range 2026 Review

There were three bikes on offer at the 2026 Beta RX motocross launch: the Beta RX 250 2T, the Beta RX 350 2T, and the Beta RX 450 4T.

The launch was held at a private track in Lismore, NSW, where we were treated to excellent conditions. The hard-pack, slightly undulating track had benefited from earlier rain, making for an ideal setting.

With not many manufacturers pushing two-stroke motocross bikes, Beta sits in a unique position with its RX 250 2T and its industry-first RX 350 2T. These two bikes help bridge the gap to Beta’s competition in the 450 class.

Shared across the entire RX range is a steel frame with an updated cast-in brace around the steering stem for increased stiffness. Also standard are KYB fork and shock, Nissin brakes with Galfer discs, XTRIG FlexFit handlebar mounts, electric start, a lightweight chain, and two switchable engine maps. The 450 additionally offers four levels of traction control.

Pricing for the new Beta range is highly competitive. The RX 250 2T starts at $14,495. While that doesn’t make it the cheapest 2T motocross option – the GASGAS MC 250 comes in at $13,395 – it does undercut the KTM 250 SX at $14,695.

The RX 350 2T is in a class of its own and is priced at $15,495. That’s a strong price for something new and innovative, and only slightly above KTM and Husqvarna’s 300 2T models, which sit just under $15k.

Finally, the range-topping RX 450 4T comes in at $14,495, representing a $1000 reduction from the 2025 model. That makes it one of the cheaper 450 4T models in the segment, equal to the GASGAS MC 450F.

Beta RX 250 2T

For me, this is exactly what you expect a 250 2T motocross bike to be. The power isn’t crazy, but by keeping the revs up and using the clutch, you can maintain plenty of momentum. There’s nothing better than trying to stretch the throttle cables on a bike, and that’s exactly how I think a smaller 2-stroke should be ridden.

I’m very familiar with steel frames, and this bike has great feel. It’s well balanced, with excellent tyre feedback that gives the impression of loads of traction. The suspension also has a nice overall feel with no harsh spots, though it is a little too soft for me.

Beta RX 350 2T

This was the bike I was most excited to ride, and it didn’t disappoint. It features a dual-spark-plug head designed to deliver greater torque, smoother power, and improved rideability at lower speeds, all while still producing strong overall horsepower. I noticed this immediately after hopping off the 250.

The bike lets you hold each gear much longer than a traditional 2-stroke, which I really enjoyed. It comes standard with 14-47 gearing, contributing to its smooth, long power delivery. At the end of the day we fitted a bigger rear sprocket to test, which added a touch more punch.

Again, the bike has excellent balance and feel. Like the 250, the suspension is smooth with no harshness, but slightly too soft for my weight and speed.

Beta RX 450 4T

This is where I felt most at home, as 450s are in my wheelhouse. From the moment I got on the RX 450, I felt comfortable. The power delivery is long, smooth, and easy to ride, yet still offers plenty of punch when you want it.

I’d heard some feedback that last year’s model lacked power and had vibration at higher revs, but I didn’t experience any of that. It’s clear Beta has worked hard on refining this bike.

The 450 comes with a heavier spring rate, giving it excellent feel and improving the overall balance. The bike has a very solid, centred feel. Across all three bikes, the cockpit layout, levers, handlebars, grips, and brakes were top-notch.

I think people should strongly consider buying one of the bikes in the Beta RX range. The company has worked hard to offer machines that can be ridden at all levels, whether you’re having fun in a paddock, riding at your local club, or racing at a national level.

Beta has delivered a genuinely well-rounded production package. Balance is such an important foundation for any bike, and Beta has absolutely nailed it with the RX range. These bikes allow riders to feel safe, confident, and fast. They’re competitively priced and come equipped with some of the best components available straight out of the box.
