Engineered by Honda for the cross - motocross motorcycle segment, the 2005 Honda CR 85 R Expert relies on a 84.7 cc (5.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 47.5 x 47.8 mm (1.9 x 1.9 inches) with a 8.4:1 compression ratio.
On the scales, the CR 85 R Expert measures 65.8 kg (145 lbs) dry. Rider ergonomics and chassis geometry center around a 864 mm (34 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,247 mm (49.1 in) wheelbase engineered for quick, flickable steering geometry. The 5.1-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
