CRA Class Guide Reference This guide is a courtesy to help you identify the classes that your bike may qualify to race in. Please refer to the CRA Rulebook for specific questions regarding classes. You may “bump up” to a larger weight class, but Supersport rules remain in effect. For example, you may not run a LW Superbike in the MW Supersport class even though you are at a disadvantage. Supersport rules are the most stringent and are adhered to regardless of weight class.
