2024 Beta 250 RR Technical Information

Features and specifications of Beta’s standard-model 250 two-stroke enduro.

Let’s face it: Not every Beta rider wants, or needs, the outright performance of a Race Edition model. The Italian manufacturer knows that for many off-road enthusiasts, a standard RR model is more than enough bike. The 2024 Beta 250 RR retains a single spark plug, electric start, counterbalanced, Keihin PWK 36mm carburetor-equipped 249cc two-stroke engine with a six-speed transmission, but also utilizes electronic oil injection to keep things simple when refueling. Straight gas is easier for most to obtain, whether trailside or topping off at your local station, and the convenience is hard to beat. Read on to learn more about the 2024 Beta 250 RR, which is priced competitively at $9,899.

Behold: The 2024 Beta 250 RR in its natural habitat. An all-red theme with black rims differentiates the RR models from the Race Edition off-road and RX motocross lines the Italian manufacturer offers.Mark Kariya
The carbureted liquid-cooled two-stroke 249cc single-cylinder engine has a six-speed transmission, is counterbalanced, and still utilizes the Beta Progressive Valve (BPV) for extensive tuning possibilities. Keihin’s PWK 36mm carburetor and Moto Tassinari VForce4 reed block are also standard equipment.Mark Kariya
Arrow supplies a beautiful plated pipe. The 250 RR features a traditional 66.4 x 72.0mm bore and stroke, along with a single spark plug design (unlike its 300 RR and 300 RR Race Edition big brothers). Classified as an enduro off-road platform, there are many similarities with the 250 RR Race Edition.Mark Kariya
Carbureted bikes are alive and well! The Keihin PWK 36mm carburetor ran perfectly during our time with the bike. Unlike the 250 RR Race Edition that requires premix fuel, the standard 250 RR utilizes an electronic oil-injection system, fed just before the reeds.Mark Kariya
Long silencer, smooth power delivery. The 250 RR emits a rather quiet tone for how much horsepower lurks inside—39.7 hp and 27.2 lb.-ft. of torque on the Dirt Rider dyno, to be exact. The plastic heat shield keeps boots and leathers safe.Mark Kariya
The two-stroke oil reservoir is located under the seat, which features a push-button removal system. A Twin Air air filter comes standard and fits the plastic cage like a glove. No-tools servicing and quick access are Beta trademarks.Mark Kariya
New radiator shrouds are narrower than ever and fit seamlessly with the translucent 2.5-gallon gas tank. The radiators themselves are lightly reinforced on the backside with cross bracing.Mark Kariya
The petcock has three positions: on, off, and reserve. The translucent tank makes it easy to keep an eye on fuel, but don’t be alarmed if you have to switch to reserve earlier than you expect: Beta wants to be sure you make it home.Jeff Allen
Easy-to-spot engine map button. The sun icon is full power, while the rain map softens the hit substantially and also mutes top-end and over-rev.Mark Kariya
Engine start and stop combination switch can be found on the rider’s right side of the handlebar. Although lacking hand guards in stock trim, there’s plenty of space to add them later. Domino throttle housing and glue-on grips are also standard equipment on all Beta models, 250 RR included.Mark Kariya
Handlebar comes set in the middle location, though Beta offers a variety of positioning for riders of all shapes and sizes. The ZF Sachs 48mm open-cartridge coil-spring fork offers spring preload, compression damping, and rebound damping adjustment—all up top on the fork caps. Toolless adjustability makes trailside changes a breeze.Mark Kariya
The ZF Sachs shock offers spring preload, low- and high-speed compression damping, and rebound damping adjustment. Also pictured is the kickstarter plug on the side case, an optional extra for those who do not fully trust electric starting and batteries just yet. It and many other items can be purchased from the get-go using the Build Your Own Beta (BYOB) program or at a later time through Beta accessories.Mark Kariya
The red knob high-speed compression-damping adjuster can be turned by hand with settings based on clicks, not turns, making it easy to adjust mid-ride. Plus sign is stiffer, minus sign is softer. The gold low-speed compression damping clicker and rebound damping adjustment (located on the shock clevis) require a screwdriver to adjust.Jeff Allen
Beta has different triple clamps between many models, but they are all engraved with proper torque settings: 17 Nm upper, 12 Nm lower. Fork height is set at line 1 in standard form. Raising the fork legs in relation to the triple clamps increases front wheel weight bias, whereas lowering them to flush with the top caps will calm down the handling.Jeff Allen
Black accented swingarm and lower chain guide. On other Beta models including the Race Edition off-roaders and RX motocrossers, red is the color of choice for the chain guide. Personally, I like the simpler look with no swingarm sponsor logos. Also note, there’s plenty of room in the swingarm for rear axle placement.Mark Kariya
Maxxis MaxxEnduro tire in 90/90-21 sizing, black Excel Takasago rim, Nissin dual-piston brake caliper, and Galfer 260mm solid brake rotor up front.Mark Kariya
Maxxis MaxxEnduro tire in 140/80-18 sizing, black Excel Takasago rim, Nissin single-piston brake caliper, and Galfer 240mm brake rotor in the rear—and some actual riding evidence on this testbike! With over 200 miles logged on her at time of photos, the minimal rear rotor wear and swingarm scuffs show how well the package holds up.Mark Kariya
Even though the 250 RR is one of Beta’s most affordable bikes, the quality coated Nissin front brake master cylinder and steel-braided brake line remain standard components. Strong stopping power on heavier Beta four-strokes means superb control and feel on the lighter two-stroke models.Jeff Allen
A Kokusan AC-CDI ignition powers the headlight. Dedicated night riders may want to invest in something a little more powerful. However, for the recreational rider, the stock unit will get you back when the ride runs long. Behind the shell, one can see the horn assembly and visualize the mounting procedure: Two black rubber straps secure the entire assembly.Jeff Allen (left) / Mark Kariya (right
Headlight low- and high-beam switch on the rider’s left, with the horn button on the ready as well.Jeff Allen
The 250 RR dashboard is simple by design and intuitive to use. It displays mileage, trip distance, engine hours, and time. Although this particular unit was not brand new, I prefer to test bikes with a few hours on them whenever the occasion arises.Mark Kariya
More trailworthy and beginner-friendly than comparable Race Edition models, the 250 RR fills a niche many riders should appreciate. It’s easy to own and operate thanks to dedicated settings and electronic oil injection allowing straight gas to be used, and also a bargain at $9,899.Mark Kariya
