This past weekend was the 2024 ISR Spring Rules meeting, at this time there is no new ISR rule changes for the 2025 season.
We are working on updating the Cor PowerSports series rules as there will be some changes for the upcoming season.
The 2025 rider number list has been updated on the website today, all 2024 numbers are reserved until October 1, 2024. All rider numbers listed are reserved, any number not listed is available for new members or current members who wish to change their assigned number.
NO duplicate numbers or numbers with letter designation are allowed.
Number backgrounds are required to be white with black numbers or black with white numbers on the side of the snowmobile and Hi Vis on the windshield.
Chassis numbers imprinted on the tunnel must be visible, this is not only needed for machine identification for Pre and Post tech but also mandated by DNR regulations.
This summer we will be attending Hay Days September 7-8 and have the same booth space EC1 that we have traditionally been, we also have been invited to participate in the professional racing display for the 70th Anniversary celebrating at Polaris in Roseau, MN August 17-18, 2024. We will be bringing the 48’ command center trailer and some of our course marshal machines with to display.
We are working on finalizing details for some exciting things for the 2025 race season that we look forward to announcing over the summer.
Only 247 days until the season opener of the Dunmire’s 100 in Brainerd, MN!!
