Overview

Introducing the 2008 Beta Alp 125, a remarkable blend of agility and performance within the trial motorcycle category. Known for its exceptional handling and lightweight design, the Alp 125 caters to riders who seek adventure in challenging terrains. Whether you’re a novice looking to hone your skills or a seasoned rider wanting a dependable companion for trials, this model is engineered to meet your needs with precision. With a solid reputation in the off-road community, Beta has crafted a motorcycle that stands out for its balance of power and ease of use. At the heart of the Alp 125 lies a robust 124cc single-cylinder four-stroke engine that delivers an exhilarating ride. With a compression ratio of 10.5:1, the engine offers solid torque and smooth acceleration, making it well-suited for navigating the intricate obstacles of trial riding. The efficient Mikuni UCAL 5Nh carburetor ensures optimal fuel delivery, while the air-cooled system keeps the engine temperature manageable during intense rides. Paired with a 5-speed gearbox and a wet multi-disc clutch, the Alp 125 provides seamless shifting and responsive power delivery, allowing riders to tackle steep inclines and tricky descents with confidence. The Alp 125 is equipped with a steel double cradle frame that promises durability and stability, essential for tackling rugged trails. Its advanced suspension system features a hydraulic fork with 170 mm of front travel and a monoshock rear with 180 mm of travel, ensuring that bumps and jumps are absorbed effortlessly for a smoother ride. The braking system, comprising a 245 mm front disc and a 220 mm rear disc, offers reliable stopping power. Additionally, with a ground clearance of 298 mm, this motorcycle can easily navigate rocky paths and uneven surfaces, enhancing its off-road capability. The dual starting options—electric and kick—add convenience, making it easy to get going in any situation. **

Pros

  • Lightweight and Maneuverable: Weighing just 101 kg, the Alp 125 is easy to handle, especially for new riders or those tackling tricky trails.
  • Responsive Engine Performance: The single-cylinder four-stroke engine provides smooth power delivery and excellent torque for trial riding.
  • Durable Suspension System: With adjustable rear suspension and sufficient travel, the bike ensures a comfortable ride over rough terrain.
