1967
1967
The 1967 Norton 650 SS was a significant motorcycle in Norton's lineup, arriving during a period of fierce competition in the large-capacity British twin market. This model built upon previous Norton twins, aiming to provide a sportier experience than some of its predecessors. Competitors at the time included the Triumph Bonneville T120, a machine known for its own performance capabilities and widespread appeal.
At the heart of the 1967 Norton 650 SS lies a 646.0 ccm (39.42 cubic inches) parallel-twin engine. This powerplant produces a respectable 52.0 HP (38.0 kW) at 6800 RPM, allowing the motorcycle to achieve a top speed of 185.0 km/h (115.0 mph). The engine's characteristics provided adequate power for the era, making it a capable machine for both shorter trips and longer hauls. The responsiveness of the engine contributed to the bike's sporty character.
The riding experience on the Norton 650 SS was characterized by a somewhat forward-leaning riding position, hinting at its sporting intentions. While not a fully dedicated sportbike with track-focused ergonomics, it offered a more engaged riding experience than some of its contemporaries. The suspension, while basic by modern standards, provided adequate damping for the road conditions of the time. The seat, though not overly plush, was generally considered acceptable for medium-length rides.
The 1967 Norton 650 SS appealed to riders who wanted a British twin with a sporting edge. It wasn't necessarily for the long-distance touring crowd, nor was it for those solely interested in outright comfort. Instead, it targeted individuals who appreciated the classic styling and wanted a motorcycle capable of spirited riding on winding roads. The 650 SS offered a unique character and a connection to a golden era of British motorcycling.
