2023 Class and rulebook updates
Class and rulebook updates for 2023 have been made and published provisionally on our Rules page. Rule updates will be provisional to start with, and we will be open for feedback until February 24. We're making a few tweaks based on attendance from last year in terms of classes:
Sprint classes and day-of run groups will be changing to accommodate larger lightweight motorcycles such as 250/450 supermotos and street motorcycles up to 450cc, and to add lap time based bracket classes.
For endurance racing, the 150 Spec class will be folded into the Formula Middleweight class, and the Street 125 and Supersport classes will be folded into Formula 125 class, unless there is sufficient attendance to separate any of those classes back out (i.e. 4+ entries). Scooters will be run in the Formula 125 class.
Guaranteed endurance classes will be reduced to the following:
Formula 125 + Scooter
Formula Middleweight
Open
Other classes will be added back to the endurance based on sign-ups; at least 4 teams are needed per class to include them in the event.
What is Mini Moto and The Mini Endurance Challenge?
NorthWest Mini Moto is a motorcycle road racing series for minibikes, mini motards, and scooters. NWMM puts on endurance and sprint events 3-4 times a year in eastern Washington and Oregon.
At the heart of NWMM is the endurance challenge. Endurance racing offers unique challenges and growth opportunities for riders. Team strategy, pit strategy, maintenance, and consistency are all important to win an endurance race, and riders on the team will get as much racing seat time in one event as they do in an entire season of sprint racing.
Sprint races will be held at MAC Track in conjunction with Oregon Lightweight Moto in 2023.
what do i need to race?
See the Getting Started page for more information on requirements and how to start racing.
For any mini racing, you'll need a bike and gear. For endurance racing, you'll also need a team!
A transponder is also required; one can be rented or purchased from NWMM, or purchased directly from Westhold. See the Rules or the Getting Started page for more details.
Not sure where to start? Try the Getting Started page for a list of common builds, turn-key mini race bikes, and the gear that you'll need.

Not sure enough to buy a bike? We have several vendors offering Rentals, and NWMM has several "taste of racing" demo bikes available for single sessions.
For more complete details, see the Rules page.
Can I race my motorcycle?
Sure, if it's a minibike or scooter! It may or may not be competitive, but it'll be a lot of fun. Endurance races are restricted to just minis, but our sprint races held jointly with Oregon Lightweight Moto allow larger lightweight motorcycles.
Rules for scooters are more complicated, but all scooters should be able to find a class to race with NWMM.

How much does it cost?
NorthWest Mini Moto is working to keep costs as low as possible for racers, so prices may change based on the number of previous entrants. Prices for 2021 are per-event, please see the Sign Up page for details. In 2020, the average entry cost per rider per event was ~$100. Memberships are a one-time fee to reserve your race number and are active as long as you are, see Membership for the sign-up link.
