2011 Lem RX3 Racing Technical Analysis & Specification Breakdown
At the heart of the 2011 Lem RX3 Racing minibike, cross motorcycle, Lem utilizes a 49.8 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 12.8 HP (9.3 kW) at 13,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.1 x 41.7 mm (1.5 x 1.6 inches).
On the scales, the RX3 Racing measures 42 kg (93 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 675 mm (26.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 985 mm (38.8 in) wheelbase engineered for quick, flickable steering geometry. The 2.01-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
