The North American Snow Bike Association (NASBA) has been the national sanctioning body for US motorcyclists for almost 100 years. Snow Biking is a motorcycle sport, so it makes sense to shade it under the NASBA tree. Being sanctioned by the NASBA also offers:

• Series Liability Insurance
• Rider Insurance
• Official legitimate recognition of the sport
• More exposure, clout and gravitas!
• Consistent racer classifications and rules

NATIONAL CHAMPIONSHIP CLASSES:

• Pro Men – Age 16-up (up to 450cc, 2 or 4-stroke)
• Pro Women – Age 16-up (ANY size engine, 2 or 4-stroke) (Note, women over 16 CAN also enter in any of the men's classes if they wish, veteran too if over 40.)

Please visit Rules page to understand what is allowed and not allowed on your snow bike.​

ALL riders MUST wear a helmet and goggles, chest and back protector, boots and gloves while practicing and/or racing on-site during race day.

The NASBA Championship Snow Bike Series follows the NASBA amateur motocross rule book. Obviously, there are some unique rules which apply ONLY to snow bikes, known as supplemental rules and you can read them by clicking here.

You MUST be either an annual NASBA member or buy a temporary weekend license to race. Adults CAN buy a $49 annual membership by clicking here<-->, or you can buy a $20, temporary, weekend membership at the event (and that $20 can be applied later toward an annual membership). Youth annual memberships are $29 and you can also buy a $20 temporary weekend youth membership onsite for $20, which can also be applied toward an annual membership. There also an annual family membership for $98 which buys membership for 2 adults and up to three youth members in a family. An annual NASBA membership will also work for other types of motorcycle competition such as motocross, flat track and enduro and if you are already an NASBA member, that will also allow you to race snow bikes.
