Engineered by Yamaha for the sport motorcycle segment, the 2015 Yamaha YZF-R3 utilizes a 321 cc (19.6 cu in) liquid-cooled twin, four-stroke layout. Internal engine geometry specifies a bore and stroke of 68.0 x 44.1 mm (2.7 x 1.7 inches) with a 11.2:1 compression ratio.
On the scales, the YZF-R3 measures 166.9 kg (368 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,379 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.2 L/100 km provides an estimated theoretical range of roughly 333 km (207 miles) between fill-ups.
