No offense, but it may depend on the size of you and your passenger. I'm about 225 and the wife is a wee little thing, probably about 115. It took a little while to get used to 2-up riding but we're getting good at it and the Speedmaster likes it.
Now, the other day I took a lady friend out for a short ride and it was a lot more challenging for me and the bike because, well, she's not a wee little thing...
I just ordered the touring seat for the Speedmaster. Review to follow in the next few weeks...
Other than that, GET THE BIKE. You'll love it.
