I’ve always wanted a Harley like Eval Knievel’s, but I wouldn’t mind having my old KDX200 again.
Ah yes, the venerable XR-750.
You know, for few years (’08 through ‘13, I think) Harley was selling a more modern version of the XR (as a 1200). Nice bike. It retained a lot of that classic “street-tracker” look from the original XR750. There are good used examples available for not too much money (by today’s standards, that is). I’ve seen a couple ‘09s for around $5K-$6K.
They did not sell am awful lot of them - it was definitely a niche market. However, those are the kinds of bikes that often end up being “collectible” twenty years later, so if you want one I’d recommend finding it soon.
