At the heart of the 2011 TGB Target 550 IRS atv motorcycle, TGB utilizes a 503 cc (30.7 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 19.9 HP (14.5 kW) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 39.6 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Target 550 IRS measures 364 kg (802 lbs) dry, translating to a power-to-weight ratio of 0.05 HP/kg (18.29 kg per horsepower). Rider ergonomics and chassis geometry center around a 918 mm (36.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
