On the ST1300 you:
1. lower the Centre stand until it touches the road/surface on both sides,
2. hold the left handle bar,
3. grab the handle/lever near the seat,
4. then stand on the pedal of the centre stand,
5. the bike lifts itself onto the centre stand.
I hope that makes sense.
I suspect it's the same on the ST1100.
