Your bike should be mechanically sound and in good operating condition. Spikes, sharp edges, or other impalement hazards should be removed. Tires should be in good condition with half-tread or better. No other special preparation is required.
You will be asked to sign a liability release for both the track and your coach.
Riders should have a basic set of motorcycle operating skills and some street experience. An MSF course is a great place to start if you are completely new to the sport.
You will need a complement of protective riding gear including one or two piece leathers, helmet, gloves and riding boots. Some textile suits are OK, but be warned, on the street or track, they are usually not as good as leather, and may melt into your skin in a long slide! Leather is always the best choice.
