Overview

Introducing the 2012 Beta Alp 125, a compact and versatile enduro-offroad motorcycle that expertly balances lightweight agility with robust performance. Designed primarily for trail enthusiasts and off-road adventurers, this bike makes its mark as an ideal choice for both beginners and seasoned riders seeking a reliable companion for exploring rugged terrains. With its roots steeped in Beta’s renowned reputation for quality and performance, the Alp 125 is positioned as a practical yet thrilling option for those looking to experience the thrill of trail riding without the heft of larger machines. At the heart of the Alp 125 is a spirited single-cylinder, four-stroke engine with a displacement of 124cc, delivering a satisfying punch with a compression ratio of 9.4:1. The engine is paired with a 5-speed gearbox that ensures smooth transitions across various speeds, making it not only capable but also incredibly responsive. The Mikuni BST 31 42AD carburettor fuels this engine, ensuring a precise mix of air and fuel for optimal performance, while the air cooling system keeps the engine temperatures in check during those exhilarating rides. With a wet multi-disc clutch and an impressive ground clearance of 300 mm (11.8 inches), the Alp 125 is built to tackle obstacles with ease, providing riders the confidence to push their limits on the trails. What sets the 2012 Beta Alp 125 apart is its thoughtful design and features. The bike is equipped with a hydraulic front suspension with 170 mm (6.7 inches) of travel and a rear monoshock that offers 180 mm (7.1 inches) of travel, ensuring a smooth ride over uneven terrain. The braking system features a single disc at both the front (245 mm) and rear (220 mm), providing reliable stopping power when needed. The bike’s lightweight frame, tipping the scales at just 107.5 kg (237 pounds), paired with a low seat height of 830 mm (32.7 inches), makes it accessible for a wide range of riders. Plus, with both electric and kick-start options, the Alp 125 is always ready to roar to life. **
