You’ve got some seriously smart guys in here dishing up good advice. I think you’ll be pretty excited to get involved when you see for yourself how cool the community is around here. Stock honda and DD2 would both be good fun for the reasons already mentioned.
I recently put together a stock moto package for pretty darn cheap(~4g) with good used components. It’s not nice and shiny like Rick’s new machine, but if you fit my medium seat, my kart is another candidate for a demo. I’m sure there will be plenty of early season testing that you can come out to and gather some knowledge.
