nice video
that bike would be a pretty quick canyon carver if you laced up some 17" wheels with a 120 on the front, 150 on the rear and a little suspension work
i suggest you get a $1500 car and take all the glass out of it. bypass the heater core and unplug the blower motor to drive on ice. there are a lot of people that will miss you if a cager takes you out.
I struggled with the same thing as the OP. I realize that its a demon I cant control and now my bike is for sale.
I bought a DR650 that was converted to a motard and LOVE it. I can dog the hell out of it through the gears and still not get to 100 mph. There are bikes now that have fuel...
like others have said its more about the rider than the bike. the problem is you wont know if its too fast for your maturity level until after you have owned it for awhile. if you got a ninja 500 or gs500 now you may be able to sell it for more than you paid for it april i bet
