Matchless G 3 CSR 350

1962
The 1962 Matchless G3 CSR 350 represents a significant evolution in the British motorcycle industry. Building upon the existing G3 line, the CSR variant aimed for a sportier riding experience. It entered a market already occupied by established machines such as the BSA Gold Star 350, offering a different take on the single-cylinder formula.
At the heart of the G3 CSR 350 lies a 347.0 ccm (21.17 cubic inches) single-cylinder engine. While not the largest displacement for the time, it provided sufficient power for spirited riding. This allowed it to reach a top speed of 129.0 km/h (80.2 mph). Fuel capacity was a generous 19.30 litres (5.10 US gallons), allowing for extended journeys. The motorcycle's dry weight of 179.0 kg (394.6 pounds) made it relatively manageable for riders of varying sizes, contributing to its overall agility.
The riding position on the G3 CSR 350 leaned slightly towards a more aggressive stance compared to its standard G3 counterparts. Though not featuring truly track-focused ergonomics, the footpegs offered a comfortable position. The suspension aimed to provide a balance between road holding and rider comfort, though some riders might find it firm on rougher surfaces. The single-cylinder engine produces a characteristic thumping sound, adding to the bike's character.
The Matchless G3 CSR 350 appealed to riders seeking a classic British motorcycle with a sporty edge. It would have been attractive to those who enjoyed weekend rides and clubman racing events. Its combination of manageable power, decent fuel range, and classic styling makes it a desirable machine for collectors and enthusiasts today. The G3 CSR 350 represents a snapshot of the British motorcycle industry during a period of intense competition and innovation.
