At the heart of the 2009 Yamaha YFM350R atv motorcycle, Yamaha pairs a 349 cc (21.3 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 83.0 x 64.5 mm (3.3 x 2.5 inches) with a 9.2:1 compression ratio.
On the scales, the YFM350R measures 170 kg (375 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 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
