I'll phrase the first question in my Mom's exact words, "WTF were you thinking?" (5 years later her opinion hasn't changed)
Had always wanted to ride, finally got the nerve after turning 30.
2. What was your first bike?
Yamaha XJ750. It was already 25+ years old when I got it, so a couple slow speed drops didn't really even hurt her a bit.
3. How do you feel about starting so late?
Part of me feels I'd have way better skills (especially offroad) if I started earlier. But the other part of me is glad I didn't learn to ride til I was mellowed out! By the time I learned to ride, any desire for being a hooligan was gone!
4. What bikes have you progressed to / thru?
I've since picked up a DR650 and just got a yamaha stryker. Picked up a bigger harley too soon after learning to ride (yeah I'm that guy) and never felt comfortable on it. Sold it to buy a house a couple years ago. Really learned to ride on the DR650 though.
