The Different Classes of Racing
The different types of motorcycles are grouped into competitive classes based on size and power output. The classes have changed over the years and will continue to do so in the future as the popularity of various models change and new technology leads to improvements. For instance, the 350cc class that was so popular in the 1970s no longer exists and the Superstock class started in 2002.
The following classes are currently run in local competitions… provided there are sufficient entries. For an explanation of the different types of motorcycle racing, see this page on Wikipedia.
