2005 MBK X-Limit SM Technical Analysis & Specification Breakdown
Built around MBK's super motard motorcycle platform, the 2005 MBK X-Limit SM utilizes a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 2.1 HP (1.6 kW) at 5,500 rpm while maximum torque reaches 2.8 Nm (2.1 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 42 HP per liter and a 250 rpm working window between peak torque (5,250 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 X-Limit SM measures 98 kg (216 lbs) dry. Rider ergonomics and chassis geometry center around a 900 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
