About Triumph Bonneville T120C Street Scrambler 1966

Introducing the 1966 Triumph Bonneville T120C Street Scrambler – a quintessential motorcycle that embodies the spirit of adventure and the golden age of British motorcycling. Positioned as an all-around bike, the T120C was designed to tackle both the open road and rugged trails, making it a versatile choice for riders seeking a blend of performance and practicality. With its iconic style and robust engineering, this timeless classic has earned its place in the hearts of motorcycle enthusiasts and collectors alike.

At the heart of the Bonneville T120C lies a spirited 649cc twin-cylinder, four-stroke engine that produces a gratifying 46 horsepower at 6,500 RPM. This powerplant, combined with its 4-speed gearbox and chain final drive, delivers an exhilarating top speed of 115 mph, allowing riders to experience the rush of the wind as they navigate through highways and dirt paths alike. The bike's compression ratio of 8.5:1, along with the precision of its Amal monobloc carburettor, ensures a responsive throttle and smooth acceleration. The lightweight frame, tipping the scales at just 165 kg, enhances maneuverability, making it a joy to ride whether you're cruising through city streets or tackling off-road trails.

The T120C features a classic design infused with practical technology that caters to the adventurous spirit. Its brazed lug, full-cradle frame provides stability while the telescopic front fork and swing arm rear suspension, equipped with two Girling dampers, ensure a comfortable ride over varying terrains. With high exhaust pipes that contribute to its rugged charm, the Bonneville stands out not only for its aesthetic but also for its functional attributes, such as the reliable drum brakes, which provide ample stopping power despite their vintage roots. The 9.46-liter fuel tank allows for longer journeys, while the 775 mm seat height caters comfortably to riders of various statures.

Pros:

  1. Versatile Performance: The Bonneville T120C excels in both on-road and off-road environments, making it a great choice for adventurous riders.
  2. Classic Aesthetic: Its iconic design and high exhaust pipes make it visually striking, embodying the spirit of the 1960s motorcycling culture.
  3. Lightweight and Maneuverable: Weighing in at only 165 kg, the bike is easy to handle, providing an engaging riding experience for both new and seasoned riders.

Cons:

  1. Drum Brakes: While adequate for its time, the drum brake system may not meet the expectations of modern riders seeking high-performance stopping power.
  2. Kick Starter Only: The absence of an electric start may deter some riders who prefer the convenience of modern starting systems.
  3. Limited Speed and Power: With a top speed of 115 mph, it may not satisfy those looking for exhilarating high-speed performance compared to contemporary motorcycles.

The 1966 Triumph Bonneville T120C Street Scrambler is not just a motorcycle; it’s a piece of history that captivates the imagination of those who appreciate the art of two-wheeled travel.
