1985 Honda CB 650 SC Technical Analysis & Specification Breakdown

Built around Honda's classic motorcycle platform, the 1985 Honda CB 650 SC utilizes a 655 cc (40 cu in) oil & air-cooled in-line four, four-stroke layout. Internal engine geometry specifies a bore and stroke of 60.0 x 58.0 mm (2.4 x 2.3 inches) with a 9.5:1 compression ratio.

On the scales, the CB 650 SC measures 197 kg (434 lbs) dry. Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,461 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 12.87-liter (3.4 US gal) fuel tank paired with a rated consumption of 6.19 L/100 km provides an estimated theoretical range of roughly 208 km (129 miles) between fill-ups, while factory top speed is listed at 233 km/h (145 mph).
