I gotta ask about the R6, why that bike? Almost all my non-bike friends want an R6, just interesting that so many non-bikers are attracted to that bike.
Best decision you'll ever make. Going fast on bikes is quite boring, however dragging your knee around a corner doing 30mph, knowing that if you crashed right now you would be ok and your bike would be cheap to fix, thats really the beauty of biking. PS: Just about ever pro racer I've ever met, started on a 125, as you can focus on handling not throttle position.
