Yeah I read it, and the only real overlap was where I agreed you were wrong, not sure what more you want from me.
In all seriousness, not everyone wants a $20k bike to START riding track. You can probably pick up a well setup sv650 for under $4k with everything needed as a package (warmers/stands/etc.). There's also the fact that a lot of people can't fix anything, so when they do bin it, not only does it cost a fortune, but motorcycle shops are busy in the summer so it could be a while before they get the bike back.
Yeah, it wasn't very good advice. Just another point of view.
If you get a track bike, no reason why you couldn't plate it and run it on the street as well. But it would suck if that was your only motorcycle.
If I were to do it again, I'd probably do the same again. I got to ride some pretty cool bikes on the track!
