Engineered by Yamaha for the sport motorcycle segment, the 1984 Yamaha RZ 350 relies on a 347 cc (21.2 cu in) liquid-cooled twin, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 64.0 x 54.0 mm (2.5 x 2.1 inches) with a 6.0:1 compression ratio.
On the scales, the RZ 350 measures 168 kg (370 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,385 mm (54.5 in) wheelbase engineered for quick, flickable steering geometry. The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
