The 1964 Norton 650SS: A Classic All-Rounder

The 1964 Norton 650SS stands proudly as a stalwart of British motorcycle engineering, seamlessly blending classic aesthetics with formidable performance. Positioned as an all-rounder in the market, the 650SS was designed to cater to the needs of everyday riders while also appealing to those with a passion for spirited riding. With its iconic styling and robust build, this motorcycle has captured the hearts of enthusiasts and collectors alike, solidifying its place in the pantheon of classic motorcycles.

At the heart of the 650SS lies a potent 646cc twin-cylinder, four-stroke engine that churns out an impressive 52 horsepower at 6800 RPM. This lively power output allows the bike to reach a top speed of 185 km/h (115 mph), making it a thrilling option for both city commuting and long-distance touring. The engine's 8.9:1 compression ratio, combined with a responsive carburettor fuel system, ensures smooth acceleration and a satisfying power band. Riders can expect a dynamic experience, amplified by the bike's lightweight profile of just 196.9 kg (434 pounds) that contributes to agile handling and cornering prowess.

The Norton 650SS is equipped with a suite of features that enhance both performance and rider comfort. Its duplex steel cradle frame provides stability and strength, while the telescopic front suspension and dual chocks at the rear offer a cushioned ride over varying road conditions. The drum brakes at both front and rear deliver reliable stopping power, though they require a bit of finesse compared to modern disc systems. With a fuel capacity of 13.5 liters (3.57 gallons), riders can enjoy extended journeys without frequent stops at the pump—an essential trait for those looking to embark on weekend adventures.
