and as far as that 18 year old that bought a 'busa on a card.....he was striving for his darwin award to begin with. Who in their right mind buys a $15K bike on 20% interest? You have any idea what 18 year old with the worlds fastest production street bike would cost for insurrance? What high school kid could afford about $500 for the 'loan' and another about $2K for insurance?
I am not saying everyone should get X bike to learn on....Hell, I work with a kid that had a Triumph Daytona at 17...and wrecked in 2 weeks cause his uncle told him to take it on the highway. I am saying that if you required a specific size for all, it will not work.
