2017 Ariel Ace Technical Analysis & Specification Breakdown

Positioned in Ariel's sport motorcycle lineup, the 2017 Ariel Ace relies on a 1237 cc (75.5 cu in) liquid-cooled v4, four-stroke powerplant. In factory specification, peak output is rated at 173 HP (126.3 kW) at 10,000 rpm while maximum torque reaches 131 Nm (96.6 lb-ft) at 8,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 139.9 HP per liter and a 1,250 rpm working window between peak torque (8,750 rpm) and peak power (10,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

Rider ergonomics and chassis geometry center around a 745 mm (29.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,541 mm (60.7 in) wheelbase engineered for planted straight-line stability. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 266 km/h (165 mph).
