What classes can i race my 89 CBR 600 in? Also, i need to get a belly pan made for it, any suggestions?
Your best bet is Heavyweight Sportsman, running with the likes of SV650's and Aprilia 250's. Sportsman classes are fun racing, perhaps even moreso now that points earned there don't count toward the overall championship. After that you're in all the standard middleweight classes: Superbike, Supersport, GP, and GTU. In those classes you're up against all the modern 600's and you'd be hard pressed to be very competitive with that bike.
