YAMAHA YZ250F (2005-2006) Specs, Performance & Photos

If it's got an F suffix, it's a 4-stroke, so we're looking at a smooth engine powering the 2005 YZ250F. However, this quarter-liter bike is nothing like a tame beast: it packs more power than meets the eye, and thanks to its 5-speed transmission, there's also torque on tap for fast starts on the dirt track and confident uphill strides on forest trails.

2005 brings a lot of engine revisions, and suspension also received massive tweaking for a more balanced performance and predictable steering. The rear caliper is new, and the bike got premium Excel rims, too, complemented by a new flat seat and repackable exhaust.
