I live in Wisconsin and cannot find anything if this is legal or not. I recently bought a 1985 Yamaha Tri-Moto 125 three wheeler and it was last registered in 2007, I also got a Honda ATC 200 with a blown engine that was registered in 2012 with the sticker valid until 2014. Anyway I was curious if I could put the stickers off the Honda onto the Yamaha and ride it with those until I can register it next summer?

 

I don't know about Wisconsin but in Michigan it's illegal to transfer the sticker from one atv to another. It even says so on the other half of the sticker. I wouldn't be surprised if it's the same there.
