2023 Beta 350 RR-S Technical Information

Features and specifications of Beta’s 350 four-stroke dual sport bike.

September 11, 2023

Street-legal motorcycles are a dime a dozen, as are the typical off-road machines we frequently test here at Dirt Rider. While the entirety of Beta’s RR-S models are street-legal in all 50 states, the Italian manufacturer wisely promotes them as full off-road motorcycles used to legally connect trails. This versatility and balancing act is achieved by blending quality components as well as relying on Beta’s philosophy of “Rideability.”

The 2023 Beta 350 RR-S is the smallest displacement out of the 350, 390, 430, and 500 range, but provides more confidence for average riders. Producing a true “street-legal off-road” model is a difficult endeavor, yet Beta has managed to find the secret sauce with its RR-S lineup. Read on to learn more about this unique displacement offered in the Beta catalog.

The 2023 Beta 350 RR-S in its natural habitat. Billed as street-legal off-road models, all renditions in the RR-S line are exceptionally equipped to handle off-road riding.Jeff Allen

Right-side engine detail shot. Electronic fuel injection (EFI) with dual injectors ensures smooth and easy-to-use power. “Rideability” is Beta’s slogan, and the 349cc displacement is right up this alley. Even with a 13.2:1 compression ratio, the 350 RR-S mill remains free-revving and easy to ride. With separate engine and transmission oils, the Italian engine design is well engineered. The diaphragm clutch offers light pull, and three spring options allow owners to customize feel. Adding a kickstart assembly remains an available option for those of us worried about ever losing juice.Jeff Allen

Left-side engine closeup. Equipped with a wide-ratio six-speed transmission, Beta includes a 13-tooth countershaft sprocket for its off-road-focused users with every new bike purchase. The 15/48 standard ratio is good for all-around dual sport use. It also comes equipped with proper frame guards and skid plate: Ready to hit your local trails, even if pavement separates the fun sections.Jeff Allen

With a dual injector system and optimized airboot, the small-displacement Beta runs better than expected. Designed as an everyman bike, this machine is great for entry-level dual sport riders and those who do not require outright horsepower for enjoyable two-wheel excursions.Jeff Allen

The 350 RR-S header is tucked nicely away from potential hazards with its center-port exhaust.Jeff Allen

A spark arrestor–equipped muffler comes standard and the guard ensures that leathers stay fresh on long rides.Jeff Allen

A radiator fan is hidden away behind the left radiator and in front of the translucent 2.4-gallon gas tank.Jeff Allen

Neatly mounted on the top frame tube and in front of the gas cap, Beta’s engine map and traction control switch is easily visible and less susceptible to handlebar damage. Featuring two-position map settings for rain or shine and traction control, the Beta design allows users multiple options for changing conditions. Traction control is a new feature in 2023 for the RR-S models.Jeff Allen ,Jeff Allen

Engine start and stop buttons are on the right side of the handlebar, easy and intuitive to use. The front brake clamp doubles as a mirror attachment point (though we removed the right-side assembly).Jeff Allen

The ZF Sachs 48mm open-cartridge coil-spring fork features toolless suspension adjusters including compression (right leg), rebound (left leg), and spring preload (large turn knob located on the right leg).Jeff Allen

The ZF Sachs shock offers adjustable high- and low-speed compression on the body. The red knob controls high-speed compression, while the gold flat-blade adjuster controls low-speed compression. The aluminum spring preload locks are easily accessible as well.Jeff Allen

Rebound adjuster located down low by the linkage assembly. Clockwise adjustments slow the action down, while counterclockwise adjustments speed it up. Another positive rear suspension design: The shock can be removed without lifting or removing the subframe. Simply remove the muffler, then remove the top and bottom shock bolts. The shock can be pulled out through the right side of the subframe.Jeff Allen

The black and silver swingarm immediately stands out, while 21-inch front and 18-inch rear Excel rims come standard. Beta’s mix of red, black, white, and silver is eye-catching.Jeff Allen

More black accents with the triple clamps. With six positions available for the handlebar mounts, tailoring your ride is easy with Beta.Jeff Allen

Proper Italian lines and styling grace the RR-S models. The entire 2023 Beta dual sport line sees upgraded radiator shrouds that are narrower than before, giving riders more freedom of movement especially when cornering. Note that the radiator cap is located on the left side as well.Jeff Allen

Right-side radiator shroud and horn location. As off-road worthy as this bike is in standard trim, it’s easy to forget such necessities that make it 50-state compliant.Jeff Allen

Smooth lines and a thin seat grace the 350 RR-S. The seat’s push-button removal design remains, as does Beta’s quick-change air filter system: No tools required. Long-distance riders will find comfort knowing that aftermarket seat manufacturers produce numerous options for the notoriously firm stock assembly.Jeff Allen

A Trail Tech Voyager GPS unit comes standard. It has more than 40 functions like trip- and hourmeters, engine and outside temperature displays, altitude readings, downloadable trail maps, as well as many more features. New owners should certainly invest some time into learning its operation, as it’s a valuable resource for riders young and old.Jeff Allen

Plenty of stopping power on the 350 RR-S. With Nissin components, a 260mm front rotor, and steel-braided line, the 265-pound (wet, as measured on Dirt Rider’s automotive scales) machine can get slowed down in a hurry. Beta uses one of the most interesting fork guard designs in the industry, with a curvature unique to themselves.Jeff Allen

High-performance Nissin brakes with steel-braided lines, front and rear. The 240mm rear rotor is a good pairing with the 260mm front.Jeff Allen

Proper hand guards come standard and the Nissin front brake master cylinder is extremely off-road worthy. Beta does not detune its dual sport brake components like other competitors…Jeff Allen

Love me some glue-on grips! Note the light controls right close to the grip as well; easy to access and control to keep your mind on the adventure ahead.Jeff Allen

Proper headlight and turn signals keep the RR-S lineup 50-state legal.Jeff Allen

Rear turn signal shapes match the aggressive styling of the fronts.Jeff Allen

Ready to tackle any terrain, the 350 RR-S is the easiest to maneuver out of Beta’s 350, 390, 430, and 500 options. At $11,499, it’s a bargain for what you’re getting in the dual sport world.Jeff Allen
