On the scales, the RR Motard 4T 125 LC measures 108 kg (238 lbs) dry. Rider ergonomics and chassis geometry center around a 886 mm (34.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,439 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 7.3-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
