At the heart of the 2008 Yamaha YZF-R6 sport motorcycle, Yamaha pairs a 599 cc (36.6 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 67.0 x 42.5 mm (2.6 x 1.7 inches) with a 13.1:1 compression ratio.
On the scales, the YZF-R6 measures 166 kg (366 lbs) dry. Rider ergonomics and chassis geometry center around a 851 mm (33.5 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,379 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 17.41-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
