Overview

Introducing the 1979 Cagiva SX 350, a true gem in the world of enduro-offroad motorcycles. Born from the innovative spirit of Cagiva, this motorcycle was designed to tackle the rugged terrains and demanding trails that enthusiasts crave. With a blend of Italian flair and robust engineering, the SX 350 made its mark as a versatile companion for both seasoned riders and newcomers to the off-road scene. As the late '70s ushered in a wave of off-road enthusiasm, the SX 350 stood out for its performance and reliability, appealing to a broad spectrum of riders looking for adventure. At the heart of the SX 350 lies a spirited single-cylinder, two-stroke engine, boasting a displacement of 342cc. This powerplant churns out an impressive 27 horsepower at 6000 RPM, allowing riders to experience exhilarating top speeds of 132 km/h (82 mph). Its 9.6:1 compression ratio and well-tuned bore and stroke dimensions (80.0 x 68.0 mm) ensure a punchy, responsive throttle, making it perfect for navigating steep inclines or cutting through dense woods. The air-cooled engine pairs seamlessly with a 5-speed gearbox, allowing smooth gear transitions, whether you're climbing rocky paths or cruising along dirt trails. This combination of power and agility offers a thrilling ride that keeps you engaged mile after mile. The SX 350 is equipped with features that enhance both performance and rider confidence. The expanding brake system at both the front and rear provides reliable stopping power, crucial for tackling off-road obstacles. With a total weight of 139 kg (306.4 pounds) and a fuel capacity of 9 liters (2.38 gallons), the SX 350 strikes a balance between robust construction and manageable handling. This lightweight design, combined with its rugged frame, allows riders to maneuver effortlessly through challenging conditions. Cagiva’s commitment to quality is evident in the SX 350’s design, ensuring that it remains a durable option for those looking to push their limits on the trails. **

Pros

  • Powerful Engine: The 342cc two-stroke engine delivers excellent power-to-weight ratio, making it capable on various terrains.
  • Lightweight Design: At just 139 kg, the SX 350 offers nimble handling, giving riders the confidence to tackle tricky trails and obstacles.
  • Durable Construction: Built to withstand the rigors of off-road riding, this motorcycle showcases Cagiva’s commitment to quality and reliability.

Cons

  • Limited Braking Technology: The expanding brake system, while effective, may lack the advanced performance of modern disc brakes.
