Big Boy Kitty Kat Series is a family-oriented youth snowmobile racing organization for drivers ages 2–17. Every Saturday, January through February, kids race — and run the show: flagging, announcing, tech inspection, and the national anthem.
Founded in the late 1990s, organized as an LLC in 2014, and awarded 501(c)(3) status in 2021 — BBKKS has been a Wisconsin winter tradition for over two decades.
From Little Kitties instructional laps to Open Modified competition, every driver has a class that matches their age and experience — see the full breakdown on the Rules page.
Beyond the track, youth participants flag, announce, sing the anthem, and perform technical inspections — all with the oversight of volunteer parents.
Got a kid who wants to race but no sled yet? KK Box & 120 Box Stock sleds are available to rent for beginner racers.
