Positioned in Yamaha's enduro - offroad motorcycle lineup, the 2004 Yamaha TT-R 225 features a 223 cc (13.6 cu in) air-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 70.0 x 58.0 mm (2.8 x 2.3 inches) with a 9.5:1 compression ratio.
On the scales, the TT-R 225 measures 117.5 kg (259 lbs) dry. Rider ergonomics and chassis geometry center around a 869 mm (34.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,372 mm (54 in) wheelbase engineered for quick, flickable steering geometry. The 10.21-liter (2.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
