1977
The 1977 Triumph T140V Bonneville Silver Jubilee is a distinctive machine in Triumph's storied history, commemorating Queen Elizabeth II's 25th year on the throne. This special edition Bonneville, while sharing its core with the standard T140V, offered a unique aesthetic package that set it apart. It emerged during a period of intense competition for British manufacturers, vying for market share against formidable Japanese rivals like the Honda CB750 Four and the Kawasaki Z1, which were pushing boundaries in terms of reliability and performance.
At its heart, the Silver Jubilee housed a 750.0 ccm (45.77 cubic inches) twin, four-stroke engine, a familiar and well-regarded powerplant for the Bonneville line. This unit propelled the motorcycle to a top speed of 177.0 km/h (110.0 mph), a respectable figure for the era. The bike's dry weight of 179.2 kg (395.0 pounds) contributed to its handling characteristics, offering a balance of stability and agility. Fuel capacity was 10.59 litres (2.80 US gallons), providing a reasonable range for touring or spirited rides.
Riding the T140V Bonneville Silver Jubilee offered a classic British motorcycle experience. With a seat height of 787 mm (31.0 inches) at its lowest setting, the ergonomics generally favored a comfortable, upright stance, suitable for varied riding. The twin-cylinder engine delivered a characteristic thrum, and its power delivery was predictable and engaging. While not designed for track-focused antics, its road manners were generally well-received, providing a direct connection between rider and machine, a hallmark of motorcycles from this period.
The 1977 Triumph T140V Bonneville Silver Jubilee appealed primarily to enthusiasts of classic British motorcycles and collectors seeking a unique, commemorative edition. Its appeal lay in its heritage, the traditional twin engine, and the specific aesthetic details that marked it as a Silver Jubilee model. It was a motorcycle for those who appreciated mechanical simplicity, a distinctive sound, and a tangible link to a significant moment in both British and Triumph history.
