Built around Excelsior's allround motorcycle platform, the 1939 Excelsior J. 14 500 Manxman utilizes a 498 cc (30.4 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 82.0 x 94.0 mm (3.2 x 3.7 inches) with a 6.7:1 compression ratio.
On the scales, the J. 14 500 Manxman measures 164.3 kg (362 lbs) dry. Rider ergonomics and chassis geometry center around a 711 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,334 mm (52.5 in) wheelbase engineered for quick, flickable steering geometry.
