Once a little-known Italian motorcycle manufacturer, Beta has been making waves in the off-road world for the past ten years. The company’s low-slung, lightweight Xtrainer has been a huge success, providing shorter riders with the perfect weapon for weekend single-track rides. They also joined the ranks of AMA Supercross with the Liqui Moly Beta Factory Racing Team and hired Benny Bloss and Michel Oldenburg to run a pair of Beta 450 RX motorcycles.
Now, the Rignano sull’Arno-based factory is expanding its Motocross lineup with the introduction of the Beta 250 RXF, an all-new platform powered by a dual overhead cam four-stroke motor with a “piston design that comes straight from F1 technology.” according to beta.
The 250 RXF joins the 450 RXF (formerly 450 RX) along with the 250 and 350 RX two-stroke models to complete the brand’s Motocross offerings.

The 250 RXF features a dual-injector electronic fuel injection system that feeds a 249.3cc twin cam four-stroke with electric start. Beta claims the bike weighs in at 222.6 pounds, likely thanks to the aluminum center case and magnesium ignition, clutch, and valve covers. The motor is mated to a five-speed transmission that has been “completely redesigned for this engine and features optimized geometry to reduce weight and size without compromising power.” The result is a light and compact gearbox, perfect for banging the gears around your local Motocross track.
The new 250 RXF uses a KYB front fork and rear shock, which are specially valved to suit the bike’s light weight. The Excel wheels are wrapped in Dunlop MX34 tyres, with Nissin handling braking duties.
For 2027, the Beta 450 RFX returns with an updated electronics package that includes launch control and a quick shifter. This is in addition to the traction control and dual-map settings that were introduced on the 2026 model. To improve power output, a new tapered throttle body has been added, offering better pull out of corners and a broader midrange.

As expected, there are no new additions to the two-stroke Motocross line from Beta, with the return of the 250 RX and 350 RX. The 350 RX features a new piston that saves weight as well as reduces friction, resulting in a 1.5-hp gain, while the 250 RX benefits from updated final gearing to improve starts. Both models also get a new muffler which is stronger than the existing models.
Although pricing was not announced, the 450 RXF will be available this August, while the 250 RX, 350 RX and 250 RXF will not be available until September.
