Built around Lem's minibike, cross motorcycle platform, the 2006 Lem R3 features a 49.8 cc (3 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 12.8 HP (9.3 kW), transferring power to the rear wheel through a 1-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.7 mm (1.5 x 1.6 inches).
On the scales, the R3 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 610 mm (24 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 914 mm (36 in) wheelbase engineered for quick, flickable steering geometry. The 3-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
