Its futuristic line with the triple optical fairing and its underseat exhaust give this new ST a quite real style. The touring riders are not forgotten. A color-matched factory-designed hard luggage is available, as an optional extra.
Still a good new, the price remains unchanged compared to the 2004 model.
A version with ABS braking system appears during 2005 with a new colour "Sunset Red". For 2006, this colour is also available for the version without ABS.
