I'm just getting in to this racing thing, and was curious how the different classes are set up. I'm 29, and ride a KTM520sx. I would rate myself an amateur level rider I guess, but I've only raced once. Which classes can I race in? I noticed there's "OPEN Intermediate", "OPEN Jr", "Over 25 intermediate", "over 25 jr", and obviously the sportsmen class. Given my riding level and bike size, which classes can I race in? Thanks in advance if anyone on here knows about these classes and can help me out!
