Positioned in Honda's sport motorcycle lineup, the 2006 Honda RC51 relies on a 999 cc (61 cu in) liquid-cooled v2, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 100.0 x 63.6 mm (3.9 x 2.5 inches) with a 10.8:1 compression ratio.
On the scales, the RC51 measures 199.1 kg (439 lbs) dry. Rider ergonomics and chassis geometry center around a 826 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 18.16-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
