Positioned in Boom Trikes's custom - cruiser motorcycle lineup, the 2011 Boom Trikes Sportster pairs a 883 cc (53.9 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 52.3 HP (38.2 kW) at 5,900 rpm while maximum torque reaches 70 Nm (51.6 lb-ft) at 3,750 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 59.2 HP per liter and a 2,150 rpm working window between peak torque (3,750 rpm) and peak power (5,900 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Sportster measures 430 kg (948 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 140 km/h (87 mph).
