Engineered by Boom Trikes for the custom - cruiser motorcycle segment, the 2011 Boom Trikes Shadow 750 pairs a 745 cc (45.5 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 45.6 HP (33.3 kW) at 5,500 rpm while maximum torque reaches 64 Nm (47.2 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 61.2 HP per liter and a 2,000 rpm working window between peak torque (3,500 rpm) and peak power (5,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Shadow 750 measures 394 kg (869 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.64 kg per horsepower). The 14.6-liter (3.9 US gal) fuel tank paired with a rated consumption of 4.5 L/100 km provides an estimated theoretical range of roughly 324 km (201 miles) between fill-ups, while factory top speed is listed at 140 km/h (87 mph).
