At the heart of the 2011 Tomberlin SDX 150 ATV atv motorcycle, Tomberlin utilizes a 147.3 cc (9 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8.8 HP (6.4 kW), transferring power to the rear wheel through a automatic (cvt with f/n/r) gearbox and belt final drive. With a specific output of 59.7 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 SDX 150 ATV measures 236.3 kg (521 lbs) dry, translating to a power-to-weight ratio of 0.04 HP/kg (26.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 869 mm (34.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,204 mm (47.4 in) wheelbase engineered for quick, flickable steering geometry. The 15.9-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
