The odd course or 2 is great, but riding a bike that isnt well set up for you (suspension etc) equals crashes! Doesnt take that long to understand proper body positioning, but if you do and your bike isnt set up....you are never going to be fast.

I think Jay is saying there's a natural progression to these things. You learn to ride, you get your stock stuff sorted, you improve your riding and take it close to its limits, you begin to improve suspension & performance parts, you imprve your riding some more, you sell your trick parts and buy even tricker parts and on and on.......
What is spent on trick parts at the very beginning of peoples track lives could be better invested in track days. But everyones entitled to spend their money how they see fit.
Although, in saying all that, I know a guy who runs an almost stock ZX6R and does 2.10s at Calabogie.
