Overview

Introducing the 2007 Beta RR 50 Enduro Racing motorcycle, a compact powerhouse designed specifically for the thrill-seeking off-road enthusiast. Nestled within the competitive realm of enduro bikes, the RR 50 stands out for its agility and lightweight build, making it an ideal choice for young riders and those new to the world of off-road racing. With its striking color options, including a vibrant yellow and metal blue mix, and an eye-catching orange and grey combo, this bike not only performs but also turns heads on the trails. At the heart of the RR 50 is a spirited 49.7cc single-cylinder, two-stroke engine that delivers a punchy performance, perfectly suited for navigating tight trails and tackling rugged terrain. Its compression ratio of 12.0:1, combined with a meticulous bore and stroke of 40.3 x 39.0 mm, ensures responsive acceleration and exhilarating power delivery. The electronic ignition system paired with a Dell’Orto PHBN 16 FS carburettor provides precise fuel management, allowing the bike to thrive in a variety of conditions. With a 6-speed gearbox, riders can seamlessly shift through the gears, maximizing both speed and control while enjoying the smooth ride that the liquid-cooling system offers. The engineering brilliance of the RR 50 is further exemplified in its robust chassis and advanced suspension setup. Built on a steel double cradle frame, this motorcycle boasts a lightweight 85 kg (187.4 lbs) design that enhances maneuverability and handling. The front features a hydraulic fork with a 41 mm shaft and 41 mm of travel, while the rear suspension includes a monoshock with adjustable spring preload, providing a tailored ride experience for different trail challenges. Braking is equally impressive, with single disc brakes measuring 260 mm up front and 220 mm at the rear, ensuring reliable stopping power when navigating steep descents or sharp corners. **

Pros

  • Lightweight and Agile: At just 85 kg, the RR 50 offers exceptional maneuverability, making it easy to navigate through tight trails and obstacles.
  • Responsive Engine: The two-stroke engine delivers impressive power and acceleration, perfect for both novice riders and those looking to sharpen their skills.
  • Adjustable Suspension: The monoshock rear suspension with adjustable spring preload allows riders to customize their setup for various riding conditions.

Cons

  • Limited Fuel Capacity: With a fuel tank of only 6 liters (1.59 gallons), longer rides may require frequent refueling.
  • Height Consideration: The seat height of 930 mm (36.6 inches) may be challenging for shorter riders, limiting accessibility for some.
  • Two-Stroke Maintenance: As a two-stroke engine, it may require more frequent maintenance and attention compared to four-stroke counterparts, particularly in terms of oil mixing and exhaust cleanliness.
