Known for its lightweight design and exceptional agility, the REV 50 is a perfect entry-level machine that embodies Beta’s commitment to quality and performance. With its eye-catching aesthetics and robust build, this motorcycle is designed for those who are eager to tackle obstacles and hone their skills in the world of trials riding. At the heart of the REV 50 lies a spirited 49.90 cc single-cylinder two-stroke engine, delivering a delightful combination of power and responsiveness. With a compression ratio of 14.5:1, riders can expect quick throttle response and an exhilarating ride. The engine is paired with a smooth-shifting 6-speed gearbox and a wet multi-disc clutch, allowing for seamless transitions and optimal control on varied terrains. Whether you’re navigating rocky trails or climbing steep obstacles, the REV 50’s lightweight frame (weighing in at just 60 kg) and impressive ground clearance of 300 mm ensures that you can confidently tackle any challenge that comes your way. The 2008 Beta REV 50 is equipped with features that enhance both performance and rider comfort. The sturdy steel frame is complemented by a hydraulic front fork with a 38 mm shaft and a monoshock rear suspension with adjustable spring preload, ensuring a balanced and controlled ride. The braking system, featuring single discs with 2-opposed pistons both front and rear, provides reliable stopping power when you need it most. With a low seat height of 620 mm, even the smallest riders can feel confident and in control, making it an ideal choice for younger enthusiasts or those just starting their trials journey. **
