The 2005 YZ125 gets a lot of revisions and updates, including more tweaking for the 1-year-old all-new lump and a new silver paint job. Yamha came up with an all-new aluminum frame for the previous model year, and it has now received a new hydro-formed swingarm, new triple clamps and new adjustable handlebars.
The Kayaba forks are also new, while the rear suspension got a matching revision. Brakes have also been updated. and a Sun Star rear sprocket adds more contact area with the chain for increased grunt.
