bro hit me up I am a sport bike stunter I ride all the time here is my site
http://www.desertvideo.com I also get paid to ride and I think you just need a 600 I personally like gsxr 600's but the zx6 is nice to... either way you really don't need anything bigger... my 600 will take any stock 1000 or busa from light to light... and you really don't need to go 200mph anyways... no need for it.. yeah it's fun but it gets old I like the speed from light to light.... it's all about gearing... I am down 2 in the front and up 12 in the back.. for a total of up 16 which takes away topend but my low end is rediclous
