Lots of good advice offered in this thread. But, IMO, it comes down to ergonomics. Which one is most comfortable for you?
I have to strongly agree. I REALLY wanted an RT until I sat on one and then later tried to ride one. I like the look a lot more than the F3. However, the F3T that I bought is so much more comfortable for me. With over 1k miles ridden in the first 2 weeks, comfort is important to me.
So far the only 2up has been with my 19yo daughter. She loves it and wants one. However, with one more year of undergrad and then grad school, its not in her budget for awhile. She is however, trying to get me to give her my Yamaha XS650 Special. She is 5'4", so with a low slung seat, that would be perfect for her - so she says. The Goldwing on the other hand, not so much.
Regards,
Don
