2024 Beta 350 RR Race Edition Technical Information

Beta’s 350 RR Race Edition is not to be mistaken for the standard model with its bold red and blue bodywork, up-spec components, and race team graphics. (Mark Kariya/)
The Italian-built fuel-injected liquid-cooled four-stroke 349cc single-cylinder engine has a bore of 88.0mm, stroke of 57.4mm, and compression ratio of 13.2:1. Cylinder head is a DOHC finger-follower design, and throttle body is a 42mm with dual injectors. Peak figures from this mill on our rear-wheel dyno are 38.7 hp and 24.9 lb.-ft. of torque. (Mark Kariya/)
Gearbox is a wide-ratio six-speed, and there’s twin oil pumps with separate compartments for engine and transmission oils. If desired, you can add a kickstarter for backup. (Mark Kariya/)
Most Beta dirt bikes have a thermostat to keep the engine at proper temperature for those in colder climates. (Mark Kariya/)
The electronics under the seat and air filter are accessible without tools. Beta uses a lightweight lithium battery and high-end Twin Air air filter. (Mark Kariya/)
The sleek and streamlined muffler has a good tone and no spark arrestor. (Mark Kariya/)
A well-designed fuel tank makes it hard to believe it holds a generous 2.4 gallons. (Mark Kariya/)
There’s an engine map switch with settings described as sunshine or rain, the latter for wet and slippery conditions, and traction control that can be turned on and off. (Mark Kariya/)
Engine start and stop switch has large buttons that are easy to reach and use. (Mark Kariya/)
Dashboard displays mileage, trip distance, engine hours, and time. (Mark Kariya/)
The most significant feature of Beta’s Race Edition models is the suspension. Up front, we find a KYB Air-Oil Separate (AOS) 48mm closed-cartridge coil-spring fork that offers 11.6 inches of travel, and compression and rebound damping adjustability on both legs. (Mark Kariya/)
Fork is complemented by a KYB C46 shock with a 46mm body and full adjustability including spring preload, low- and high-speed compression damping, and rebound damping tunability. Rear wheel travel is 11.4 inches. (Mark Kariya/)
Like Beta’s standard-model off-roaders, the Race Editions feature Nissin brakes with 260mm front and 240mm rear rotors. (Mark Kariya/)
A Race Edition–specific feature is the front axle pull for quick front wheel replacements and tire changes. (Mark Kariya/)
Beta specs its Race Editions with a dual-ring steel-over-aluminum rear sprocket for added durability in extreme muddy conditions. (Mark Kariya/)
Billet-aluminum footpegs with stainless steel gripper pins are yet another Race Edition–only item. (Mark Kariya/)
On <i>Dirt Rider</i>’s automotive scales, the 2024 Beta 350 RR Race Edition weighs 263 pounds wet. (Mark Kariya/)
