So I'm thinking ahead. My future soulmate, long story that's still in process, probably has more time in the saddle, bike that is, than I do. I'm going to take an advanced riding course soon as spring arrives here in the upper Midwest. How are the ST1300's for riding 2 up? She's a taller than average mink, I'm guessing 5'10ish. With NO extra baggage... We'll be riding together, her on her older Harley, and me on my '03, but I'm thinking we'll want to go on a 2up ride now and again. What's this ST's rep for doubling up?
