Yamaha's profilation of this bike |
Yamaha’s name is synonymous with challenging and innovative designs,and the radical new XT660X is the first production supermotard to be offered by a non-European manufacturer.
Tuned to kick out massive low to mid-range torque, this 660cc liquid-cooled fuel-injected single is equipped with lightweight 17-inch spoked wheels running with extra-wide rubber for outstanding roadholding – while the large diameter floating front disc generates plenty of stopping power. |
