Frame
From 1974 through 2004, the YZ 125 had a single backbone frame made from steel. It generally averaged from 176 to 198 lb (80 to 90 kg). For the 2005 year, however, Yamaha switched to a single backbone frame constructed from an aluminum alloy. This frame material change dropped the weight to 190 lb.(dry weight) For 2008 models, additional weight savings in the wheel assemblies and front fork suspension have yielded additional weight savings making wet weight, no gas sub-200 lb. Aluminum framed YZ125's are notably 'flickable' and sometimes this trait is seen as a drawback since they tend to become more difficult to control on rough surfaces.

Famous quotes containing the word frame:
“In this choice of inheritance we have given to our frame of polity the image of a relation in blood; binding up the constitution of our country with our dearest domestic ties; adopting our fundamental laws into the bosom of our family affections; keeping inseparable and cherishing with the warmth of all their combined and mutually reflected charities, our state, our hearths, our sepulchres, and our altars.”
—Edmund Burke (1729–1797)
“Candor is a proof of both a just frame of mind, and of a good tone of breeding. It is a quality that belongs equally to the honest man and to the gentleman.”

This universal Frame began:
From Harmony to Harmony
Through all the Compass of the Notes it ran,
The Diapason closing full in Man.”
