Vehicle Information
BETA RR 125 Dirt Bike (2018-2025)
The BETA RR 125 series (2018-2025) offers versatile off-road and dual-sport motorcycles, available in distinct 2-stroke and 4-stroke configurations. The 2-stroke models, with a 124.8 cc liquid-cooled engine, are designed for competition and off-road performance. The 4-stroke models, featuring a 124.6 cc or 124.8 cc liquid-cooled engine, cater to entry-level riders and dual-sport use. Significant updates mark the series. For 2-stroke models, a new engine was introduced in 2018, followed by major engine overhauls in 2020 (cylinder, exhaust system) and 2025 (piston, cylinder head). Race Editions, offering higher-spec components, were also introduced and refined over the years. The 4-stroke models saw extensive updates in 2021, including new electronic injection, variable valve timing, and chassis improvements. The 2025 4-stroke Race models received new crankcases. These changes represent substantial evolutions rather than simple cosmetic updates. FAQ:
