Now that right there is just about everything you need to know about about 2-up touring!OK here goes.
I wasn't going to write this much but it kept pouring out as I went along. I hope some of these ideas are helpful.
BTW, my wife gets on first. Bike on the side stand, me holding the bars, and providing a little sidestand-stress-relieving counter balance. She gets into my seat and then slides back and I get on with the standard Kung-Fu/Rockettes quarter-turn lunge maneuver.
My wife is one of those who loves the higher pillion on the stock GTL seat. She hated being "stuck behind me" on my connie, and finds the view much better on the GTL.
