Technical Overview
2011 Lem RX 65 Racing Technical Analysis & Specification Breakdown
Positioned in Lem's enduro - offroad motorcycle lineup, the 2011 Lem RX 65 Racing utilizes a 64.9 cc (4 cu in) single cylinder, two-stroke layout. In factory specification, peak output is rated at 17.4 HP (12.7 kW) at 12,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 268.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the RX 65 Racing measures 56.3 kg (124 lbs) dry, translating to a power-to-weight ratio of 0.31 HP/kg (3.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 729 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,115 mm (43.9 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.
