i know i dont need a big bike to ride fast, but a CBR600 will do over 150mph stock. And i bet more than 1/2 that track could beat me on a 1k, im looking to get into it, just not with a Katana. As far as top speed i would like a bike that i dont really find it on a CSBA ride keeping up. As far as back tracking there is a road way out in the middle of no-where, a place where a car might go by once every hour, and we have people block the roads off and if a bike is coming stop cars, but we wait if a car is going thru. We dont do what most idiots do and do 140mph around 270 columbus. BTW i ride everyday, rain or shine. I do the speed limit 90% of the time, unless im in a group thats moving faster, so i dont ride like a jackass.
