1981
The 1981 Triumph T140 ES Bonneville Royal Limited Edition represents a significant chapter in the Bonneville's storied history, arriving as the model entered its final years of production at Meriden. This limited edition variant aimed to infuse exclusivity and a touch of modern refinement into the classic parallel-twin platform. It emerged in a landscape where Japanese manufacturers, particularly Honda with its CB750 and Kawasaki with its KZ750, were setting new benchmarks for performance and reliability, offering a distinctive British alternative amidst fierce competition.
At its heart, the T140 ES Royal Limited Edition was powered by a 750.0 ccm (45.77 cubic inches) twin, four-stroke engine, a familiar and robust powerplant. This configuration allowed the bike to achieve a respectable top speed of 180.0 km/h (111.8 mph). With a dry weight of 179.2 kg (395.0 pounds), the Bonneville maintained a nimble feel despite its displacement. Fuel capacity stood at 18.00 litres (4.76 US gallons), offering a decent range for touring. The "ES" in its designation signified electric start, a welcome convenience for riders of the era, complementing the traditional kickstart.
Riding the T140 ES offered a distinctly classic standard motorcycle experience. The seat height, at 787 mm (31.0 inches) at its lowest setting, provided a comfortable reach for many riders, contributing to an upright and relaxed riding posture. The handling characteristics were predictable and stable, well-suited for cruising and enjoying the open road. While not a sport bike, its modest weight and well-balanced chassis made for an engaging ride, especially on winding country lanes where its torque delivery could be appreciated.
The T140 ES Bonneville Royal Limited Edition appealed to a specific niche: enthusiasts who valued British motorcycling heritage, a classic aesthetic, and a more direct, involving riding experience than many contemporary machines offered. It wasn't about cutting-edge performance or groundbreaking technology but rather about the enduring appeal of the Bonneville name and its distinctive parallel-twin character. This model served as a commemorative piece, celebrating the Bonneville's legacy and offering a unique, collectible iteration for those who appreciated its classic charm and British engineering.
