The machine
The 2023 Beta 390 RR is an off-road four-stroke motorcycle powered by a 386 cc, single-cylinder engine with electronic fuel injection, two injectors and liquid cooling. It pairs a six-speed transmission with a 9-liter fuel tank and long-travel suspension: a 48 mm upside-down fork with 300 mm of wheel travel and a rear setup with 295 mm of wheel travel. The listed running-order weight is 126.5 kg with a full tank and optional equipment. A 940 mm seat height and 320 mm ground clearance are useful figures to consider when checking fit and suitability for uneven terrain.
The chassis uses a 21-inch front wheel and an 18-inch rear wheel, with a 260 mm front disc and 240 mm rear disc. The RR 350–390–430–480 manual covers both Standard and Race Edition versions, so equipment details can vary by edition.
Who should ride it
This bike fits riders looking for a full-size, off-road-focused four-stroke with a six-speed gearbox and substantial suspension travel. It is a practical match for weekend trail riders and off-road riders covering varied terrain, including rough or muddy tracks where ground clearance and suspension travel matter. The 940 mm seat height and 126.5 kg running-order weight are important fit and handling considerations, especially for newer riders or anyone frequently maneuvering the bike at a standstill.
