Finding a class to ride in

Cascadia Supermoto wants you to race! If you bring a motorcycle that meets the minimum restrictions listed, we will find at least two classes for you to ride in.

The class structure has been designed to make sure that every rider has at least two classes available for them, and most should have three. If you cannot find two classes to ride in, please talk to registration or the race directory and they will make exceptions as needed to find you a second class to ride.

Restrictions for all classes

All classes have the following restrictions:

  • No sportbike-style motorcycles (i.e. fairings and clip-ons) except in the minibike and scooter classes.
    Sorry, this is a restriction imposed by one of our venues, and means that no Ninja 250s are allowed.
  • No twin-cylinder engines over 580cc unless riding in the Heavyweight class.
  • No engines with more than two cylinders unless riding in the Heavyweight class.

New class proposals

Cascadia Supermoto is open to new classes! If five or more riders wish to create a new class and are prepared to run in it, as long as it meets the general restrictions above, we will add the new class into the schedule immediately. New classes may not grid separately, but they will be scored separately and have their own championship awarded.

Sprint/Supermoto Classes

Open Supermoto

This class is for experienced racers on unlimited machinery.

You do not have to be a pro to ride this class! This is the class for the club #1 plate, and any supermoto rider who has some race experience should be comfortable riding in this class and competing for club #1. This is an amateur race series, not a pro series, and Open Supermoto is not (much of) a money class.

  • Unlimited modifications
  • Novice riders are prohibited from entering this class.

Beginner

This class is for slower riders on any motorcycle.

  • Unlimited displacement.
  • Unlimited modifications.
  • Open-class riders and riders are prohibited from this class.

Riders able to finish in the top 50% of the Intermediate class will be removed from this class. Riders with previous racing experience or extensive track day experience should not enter this class. Race direction will move riders out of this class to Intermediate and/or Open at their discretion. No season points or awards will be given in this class.

Intermediate

This class is for skilled riders who are not experienced racers, or slower racers who are less comfortable in the Open class, on any motorcycle.

  • Unlimited displacement
