Built around Lem's minibike, cross motorcycle platform, the 2005 Lem LX 4 relies on a 49.8 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. 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 LX 4 measures 49.9 kg (110 lbs) dry. Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,118 mm (44 in) wheelbase engineered for quick, flickable steering geometry. The 3.48-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
