$10K? On a budget, eh?
Fuck, I don't know, really. I recently bought what I was wanting, KTM 950 SM for 2/3rds that, next I believe it's going to be a Tuono V4, but that's $15000 or so OTD. Used Streetfighter Ducati? I'd like a Multistrada 1200S, but those are still over $10k.
A couple 2 or 3 cheaper bikes. ZRX1200 is about $3500, maybe less. You can find a 525 or 300 2 stroke KTM for $3500 or less, that's 2, you can find an old Triumph for 2 or 3 thou, if that's what your wanting. In fact, I looked at about a 68 Triumph Trophy Trail 500 last week for $3000, or it might have been $3500, which I thought was a bit high. In fact, I'm probably fucking stupid for even thinking about one of those, but I'm sort of interested. I've had a couple old Bonnevilles, and in truth, they suck, but are kind of neat, nonetheless.
Fuck, I still don't know.
