Positioned in Ariel's allround motorcycle lineup, the 1954 Ariel LH 200 Colt utilizes a 197 cc (12 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10 HP (7.3 kW) at 5,600 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 50.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the LH 200 Colt measures 123 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.3 kg per horsepower). The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 3.5 L/100 km provides an estimated theoretical range of roughly 314 km (195 miles) between fill-ups, while factory top speed is listed at 100 km/h (62 mph).
Within MotoLibrary's Ariel archive, this model family spans 6 indexed model years from 1954 to 1959, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
