Vehicle Information
BETA RR-S 390 Dirt Bike (2015-2023)
The BETA RR-S 390 is a well-regarded dual-sport motorcycle produced from 2015 to 2023. Powered by a single-cylinder, 4-stroke, liquid-cooled engine, it is valued for its robust torque delivery and predictable handling, rather than raw horsepower figures. While engine displacement remained largely consistent (around 386cc), the model received numerous enhancements over the years, particularly in its fuel injection system, chassis, and other key components. The 2015-2023 period saw significant developments for the RR-S 390. Following the introduction of electronic fuel injection (EFI) in 2017 and an upgraded chassis in 2018, the year 2020 marked a major overhaul. This included a new frame, subframe, redesigned bodywork, an improved cooling system, increased fuel tank capacity, and significant engine updates. Subsequent years brought further refinements, such as a diaphragm clutch and refined suspension settings in 2022, culminating in 2023 with optimized engine maps. FAQ:
