This would be an interesting topic to explore further. I am 6'10" and I spent over a year looking at bikes and sitting on different bikes to see what would fit. I didn't have money to buy a bike, so I could just go and sit and see what felt good. The result: NOTHING fit. The only bike that came close what the Kawasaki Vulcan 2000, which is way more bike than I wanted as my first bike.
Recently, I was lucky to get a bike for very cheap. It was an old Honda that didn't run and I didn't know much about it when I got it, it was just too good of a deal to pass up. I planned on tearing it apart and modifying the frame to make it fit. Long story short: I hopped on and it fits me just fine. Its a 1983 Honda V45 Sabre.
I'm not sure what bikes work better for taller guys, I just know all of the new bikes that I've sat on are too small. Everybody wants low seat height these days and that kills us tall guys.
So, I got lucky and found a bike for cheap that fits me well. Any other tall people out there? What has your experience been?
