At the heart of the 2002 Honda CR 80 RB Expert cross - motocross motorcycle, Honda pairs a 83 cc (5.1 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 47.0 x 47.8 mm (1.9 x 1.9 inches) with a 8.4:1 compression ratio.
On the scales, the CR 80 RB Expert measures 65 kg (143 lbs) dry. Rider ergonomics and chassis geometry center around a 876 mm (34.5 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,288 mm (50.7 in) wheelbase engineered for quick, flickable steering geometry. The 6.8-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
