Built around Boom Trikes's custom - cruiser motorcycle platform, the 2011 Boom Trikes Fighter X11 relies on a 1997 cc (121.9 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 140 HP (102.2 kW) while maximum torque reaches 190 Nm (140.1 lb-ft), transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 70.1 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Fighter X11 measures 780 kg (1720 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.57 kg per horsepower). The 47-liter (12.4 US gal) fuel tank paired with a rated consumption of 8 L/100 km provides an estimated theoretical range of roughly 588 km (365 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
