I've been riding for 6 months now on a 2002 Kawasaki Ninja 500R. I had researched what newbie bike I should purchase for months before settling on this bike. When I first walked into the dealership I honestly thought this bike is way too big, "maybe I'm biting off more than I can chew", but I always wanted to learn how to ride, so I stuck to my guns. My problem is this, I actually feel I have out grown the 500R and would like to upgrade. I have read in several forums about the bike creating complacency and overconfidence. I originally intended to purchase this starter bike and ride for 2-3 years and then upgrade to a 600cc, R6 or F4I. My problem is that I feel I've outgrown the bike and I'm feeling more of a bug to upgrade NOW! My question is this. When do you know that your skill is good enough to handle a more powerful bike, or am I being overconfident?
