2023 Endurance Schedule + 12-hour Opener

Our 2023 endurance schedule has arrived! See the Race Events section below for our confirmed endurance race dates. We've got a full 24 hours of endurance on the schedule again for this year, but we're changing up our format to keep things fresh for our veteran teams.

First up, we're super excited to bring you a special endurance event for 2023 - the NWMM 12-Hour Mini Endurance at Tri-City Kart Club! This will be our first race of 2023, our longest race ever, and will take place from noon to midnight on Saturday May 13 across multiple track configurations. We will have afternoon/evening practice on Friday May 12; exact hours are TBD.

See our Facebook page or sign up for our mailing list to stay on top of all the news.

2023 Class and rulebook updates

Class and rulebook updates are coming and will be released provisionally prior to February 1. Rule updates will be provisional to start with, and we will be open for feedback for at least two weeks after updates. We're making a few tweaks based on attendance from last year in terms of classes:

  1. The 150 Spec class will be folded into the Formula Middleweight class unless there is sufficient attendance to separate the two.

  2. Guaranteed endurance classes will be reduced to the following:

    • Formula 125

    • 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.

Sprint classes and day-of run groups will be changing as well to accommodate larger lightweight motorcycles such as 250/450 supermotos and street motorcycles up to 450cc.

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.

What's a legal minibike? Any motorcycle that fits within our Open class limits (please see the rulebook for full Open displacement rules):

  • Unlimited chassis and engine modifications except as noted.

  • Engine displacement limits:

      • 4-stroke 2-valve air- or air-oil cooled, motard frame,
        curb weight greater than 225lbs: 250cc

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.
