Overview
Introducing the 2010 Beta RR 4T 400, a motorcycle that embodies the spirit of adventure and the thrill of off-road riding. This enduro bike is designed for enthusiasts who crave the perfect blend of performance and agility on rugged terrains. With its roots firmly planted in Beta's long-standing tradition of excellence in off-road biking, the RR 4T 400 stands out in a crowded market, appealing to both seasoned riders and newcomers alike. Its striking red and white color scheme not only commands attention but also reflects the bike's racing heritage, promising an exhilarating ride every time you hit the trail. At the heart of the Beta RR 4T 400 is a potent 398cc single-cylinder, four-stroke engine, which delivers an impressive balance of power and torque. With a compression ratio of 11.0:1 and a bore and stroke of 89.0 x 64.0 mm, this engine provides robust performance across a wide range of RPMs. The Keihin FCR-MX 39 carburettor ensures precise fuel delivery, enhancing throttle response and overall rideability. Paired with a six-speed gearbox, this bike offers smooth transitions and the ability to tackle steep climbs and rugged paths with ease. Riders will appreciate the liquid cooling system that keeps the engine at optimal temperatures, allowing for prolonged adventures without the worry of overheating. The chassis of the RR 4T 400 is engineered for performance and durability, featuring a molybdenum steel frame with a double cradle design that provides excellent rigidity and stability. The 45mm hydraulic USD front forks and rear monoshock suspension system work in harmony to absorb bumps and ruts, ensuring a comfortable ride over challenging terrain. With a lightweight build of just 117.5 kg (259 pounds) and a generous ground clearance of 320 mm (12.6 inches), this motorcycle offers maneuverability and the confidence to tackle obstacles head-on. Additional features, such as an electric starter and a wet multi-disc clutch, enhance the riding experience, making it user-friendly and accessible for riders of all skill levels. **
