Overview |
| - | For 2003, the only change was the choice of colors. The previous years all had a "Red" option,
but this was replaced by a black with red flames "Special Edition" which cost an extra $100. Also in 2002, Yamaha
released the newly developed "Deltabox III" frame, which, with its hydro formed construction, dramatically reduced
the total number of frame welds, thereby greatly improving the frame's strength and torsional rigidity.
The rear end of the motorcycle was updated and streamlined with a LED taillight. This allowed for very clean
rear body lines when choosing one of several common after market modifications, such as removal of the turn
signal stalks and stock license plate bracket; and replacing them with assorted available replacements that "hug"
the body or frame. |
