Built around Yamaha's enduro - offroad motorcycle platform, the 2005 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.
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.
