Engineered by TGB for the atv motorcycle segment, the 2012 TGB Gunner 550 pairs a 502.6 cc (30.7 cu in) single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 18.9 HP (13.8 kW) at 5,500 rpm while maximum torque reaches 31.6 Nm (23.3 lb-ft) at 3,600 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 37.6 HP per liter and a 1,900 rpm working window between peak torque (3,600 rpm) and peak power (5,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Gunner 550 measures 330 kg (728 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (17.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.

Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
