Yeah, I've already had that feeling on my bicycle while riding around town at 20-25mph when a semi went by at 50 and on the motorcycle at like 60mph.
My bike is going to handle differently once I finish working on it since it's going to have new bars, fork, rear wheel, etc. I want to get a few 100 miles on it before I take the lady out on it because I want to make sure I understand how it handles etc. I think it's going to be much more stable with the gsxr wheels, not that it was unstable before.
The SV is also pretty light and nimble in general so it will feel the draft of a truck far more than a bagger would.
I don't think I'm invincible and I'm honestly pretty risk averse especially when I'm with someone else. I'm not planning on trying to impress her with the bike. I just think she'll enjoy the feeling and might be up for an hour trip every now and then if I'm dropping her home. If she's not, we can always drive. If she hates it, the jacket I bought her has removable armor and she'll wear it without it. No harm no foul.
I'm entering this with the expectation that she's not going to like it, but with the hope that she might. I don't have anything riding on this and I've told her that there's absolutely no pressure for her to do it if she doesn't like it or isn't comfortable with it.
