Overview

Introducing the 2006 Beta Alp 4.0—a standout in the trial motorcycle category that masterfully combines rugged performance with user-friendly agility. Designed specifically for both seasoned riders and newcomers to the trial scene, the Alp 4.0 is a versatile machine that excels in challenging terrains and technical maneuvers. With its lightweight frame and powerful single-cylinder engine, this motorcycle is an ideal partner for those looking to explore the great outdoors while honing their skills in extreme riding conditions. At the heart of the Beta Alp 4.0 lies a robust 349cc single-cylinder, four-stroke engine. Boasting a compression ratio of 9.5:1, this engine delivers smooth and reliable power, allowing riders to navigate steep inclines and tricky obstacles with confidence. The 6-speed gearbox transitions seamlessly, providing the necessary torque for those low-speed climbs while also allowing for spirited rides on open trails. Paired with the Mikuni BST 33 carburettor, the engine offers commendable throttle response and fuels the Alp 4.0’s impressive performance, while the air cooling system keeps temperatures in check, ensuring the bike remains reliable during longer rides. The Alp 4.0 is built with a steel frame that not only enhances durability but also contributes to its lightweight feel, tipping the scales at just 133 kg (293.2 lbs). The motorcycle features a well-engineered hydraulic front fork and a monoshock rear suspension, both providing 220 mm of travel, which translates to excellent handling and comfort over rough terrain. The braking system consists of single discs on both the front (260 mm) and rear (220 mm), ensuring effective stopping power when it counts. With a ground clearance of 300 mm (11.8 inches) and a fuel capacity of 10.5 liters, the Alp 4.0 is equipped for both short jaunts and extended adventures, making it a versatile choice for any rider. **

  • Strong Engine Performance: The powerful 349cc engine delivers excellent torque and throttle response, perfect for tackling steep inclines and tricky obstacles.
  • Versatile Suspension: With 220 mm of front and rear suspension travel, this motorcycle offers superior handling and comfort on uneven terrains.
