Not sure which one you have or even if there is much difference. I have a '96 Funduro and reading from my Service and Technical Booklet, the measurements yo have asked for are:
Height at handlebars excluding mirrors 1220mm/48.0 inches
Width from one end of the handlebar to the other end, fitted with vibration dampers 880mm/34.7 inches
Total length 2180mm/85.8 inches
Have just looked at the ST and although height is the same, the length and breadth are slightly smaller.
Hope that helps
aah! just noticed that you don't have one yet, but there obviously are some slight differences
