K1200LT does not have the rear wheel on the ground and so driving off the center stand does not work.
Generally, not being of the long inseam crowd, I find this works:
1) Do this one-up - your passenger will probably have an easier time getting on when its on the side stand, and the side stand, on solid ground, will hold you both. REALLY. Even though it does not look the part.
2) Lean to the right and plant you foot on the ground.
3) Use that foot to push
4) Sometimes it takes a rock or two - but with practice, it just comes off the centerstand.
5) Get back on the middle of the seat and plant both feet on the ground as you the bike lands and apply the brake gently if you are rolling forward.
6) Deploy the sidestand to warm it up, load passengers. set the Navigator, whatever else you do to get started.
Obstacles:
- Do not use the center stand with the front wheel uphill if its more than a slight slope. Its really hard to get of the center stand without help going uphill.
- I would hate to think what might come if you leaned the bike back far enough to get the rear wheel down, put it in 1st gear, got the back wheel to shove it off the stand with the front wheel in the air, had the front wheel come down, lifting the rear up as the centerstand snapped up and then the rear wheel came back down spinning faster than the bike was rolling. Now that sounds like a tip-over risk, plus you better hit the clutch and the brake before you hit somebody or something.
- You do need to make sure that the ground beneath your feet is solid, not sandy, full of garage dust, stones or leaf debree. That will be the only tip-over risk I have ever seen.
