1939 · Vintage
The 1939 Excelsior J.14 500 Manxman represents a significant chapter in British motorcycling history, emerging just before the outbreak of World War II. This machine was a direct descendant of Excelsior's racing pedigree, aiming to bring some of that track success to the road. In its era, it faced stiff competition from other established British manufacturers such as Norton, with their Manx models, and Velocette with the KSS, all vying for supremacy in the 500cc class.
At the heart of the Manxman was its robust 498.00 ccm (30.39 cubic inches) engine, a single-cylinder unit known for its reliability and power delivery. This powerplant propelled the motorcycle to a respectable top speed of 150.0 km/h (93.2 mph), a considerable feat for its time. Weighing in at 164.3 kg (362.2 pounds), the Manxman struck a balance between stability and agility. These figures underscore Excelsior's engineering capabilities in the pre-war era, offering a competitive package to enthusiasts seeking speed and performance.
Riding the Excelsior J.14 500 Manxman would have been a quintessential vintage experience. With a seat height of 711 mm (28.0 inches) at its lowest adjustable setting, it offered a relatively accessible riding position for many. As a vintage category machine, its riding characteristics would lean towards a more engaged, mechanical feel, typical of motorcycles from that period. The suspension would have been basic by modern standards, providing a direct connection to the road, while the brakes would have required a firm hand, demanding rider involvement.
The target audience for the 1939 Excelsior J.14 500 Manxman today is primarily vintage motorcycle collectors and enthusiasts who appreciate pre-war engineering and historical significance. Its appeal lies in its rarity, its connection to a rich racing heritage, and the authentic riding experience it offers. For those seeking a tangible piece of motorcycling history, the Manxman stands as a compelling and rewarding acquisition.
