Maine has started an antique ATV registration in 2022. Any ATV 25 years or older can be registered as an antique. The registration is also a one time deal for as long as you own the vehicle. Cost is right around 50 bucks. That's about half of a normal ATV registration.
Dont know how many members are from Maine but wanted to share this info and hopefully save someone a few bucks. I'll be registering my whole fleet as antiques when renewal time comes around.
Take care everyone
