1962
The Norton 650 SS, launched in 1962, represented Norton's effort to capture the growing demand for faster, sportier motorcycles. Building upon the Atlas platform, the 650 SS aimed to offer a more refined and performance-oriented experience. In a market filled with capable machines, the 650 SS directly competed with models such as the Triumph Bonneville T120, each vying for the attention of performance-minded riders.
At the heart of the Norton 650 SS lies its 646.0 ccm (39.42 cubic inches) parallel-twin, four-stroke engine. This powerplant provided ample power for the era, enabling a top speed of 185.0 km/h (115.0 mph). With a fuel capacity of 13.50 litres (3.57 US gallons), the 650 SS offered a reasonable range for spirited rides or longer journeys. The engine's responsiveness and robust torque made it a capable performer in various riding conditions.
The riding experience on the Norton 650 SS is characterized by its sporting intentions. The riding position leans forward slightly, encouraging an engaged feel and good control. While not a dedicated track machine, the 650 SS offers a connection to the road that many riders appreciate. The suspension, though basic by modern standards, provided a reasonably comfortable ride on well-maintained surfaces. Its responsiveness to rider input made it a fun machine to ride on twisty roads.
The Norton 650 SS appealed to riders who valued performance and classic British motorcycle styling. It wasn't designed for long-distance touring or commuting comfort. Instead, it targeted enthusiasts who sought a thrilling and engaging ride. Its combination of power, handling, and iconic design made it a desirable motorcycle for those who appreciated classic British engineering and a spirited riding experience. The 650 SS offered a raw, visceral experience that connected the rider to the machine in a way that few modern motorcycles can replicate.
