Rob,

What is your current bike? I did superstreet races 2 years ago as well as my 1st novice season last year on my 2012 KTM RC8. Not the best bike for a beginner, but i got out there and go the experience. This year I will be racing an sv650, as i feel it is a way better platform to learn on. The other great things about an SV650 is spare parts are everywhere, tires are cheaper and last longer, i can race double the classes as i could on the ktm, etc. So I will get a lot more seat time this season which equates to more learning/experience. The 250 isnt a bad platform to start on either but I think the sv650 is a solid bet as well. Hope this helps a little bit.
