Built around Yamaha's sport motorcycle platform, the 2008 Yamaha YZF-R6S features a 600 cc (36.6 cu in) liquid-cooled in-line four, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 65.5 x 44.5 mm (2.6 x 1.8 inches) with a 12.4:1 compression ratio.
On the scales, the YZF-R6S measures 161.9 kg (357 lbs) dry. Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,379 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
