2004 Suzuki JR 80 Technical Analysis & Specification Breakdown
Built around Suzuki's enduro - offroad motorcycle platform, the 2004 Suzuki JR 80 relies on a 79 cc (4.8 cu in) air-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 49.0 x 42.0 mm (1.9 x 1.7 inches) with a 6.8:1 compression ratio.
On the scales, the JR 80 measures 58 kg (128 lbs) dry. Rider ergonomics and chassis geometry center around a 685 mm (27 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,050 mm (41.3 in) wheelbase engineered for quick, flickable steering geometry. The 4.1-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
