1966
The 1966 Matchless G12 represents a significant year in the production run of this classic British motorcycle. Part of the G series lineage, which sought to offer powerful and reliable machines, the G12 aimed squarely at riders looking for a capable twin-cylinder motorcycle. In a competitive market, the G12 found itself vying for attention against established models like the Triumph Bonneville T120, offering a different take on the large-capacity twin formula.
At the heart of the Matchless G12 lies its 646.0 ccm (39.42 cubic inches) twin, four-stroke engine. This powerplant was designed to provide ample power for both touring and everyday riding. The engine produced a respectable 35.0 HP (25.5 kW) at 6500 RPM, figures that provided brisk acceleration for the era. While not the lightest machine around, with a weight of 180.0 kg (396.8 pounds), the G12's engine provided sufficient torque to manage the weight effectively.
The riding experience on the G12 is characterized by its comfortable, upright riding position, making it suitable for longer journeys. While not a sportbike with track-focused ergonomics, the G12 offered a stable and predictable ride. The suspension, typical of the period, provided a compliant ride on most road surfaces, although modern riders might find it less sophisticated than contemporary setups. The handling is generally stable, inspiring confidence in a variety of riding conditions.
The Matchless G12 from 1966 appealed to riders who appreciated classic British engineering and wanted a motorcycle capable of handling both weekend rides and longer tours. It wasn't intended for those seeking the ultimate in performance or cutting-edge handling. Instead, the G12 offered a robust and dependable package. It's a solid choice for vintage motorcycle enthusiasts looking for a piece of British motorcycling history that is relatively easy to maintain and enjoyable to ride.
