Hello, I'm looking for a used trials bike. I can find some that seem great from out of state. I'm very worried about trying to register an out of state dirt bike in CA. I don't have private property or even a back yard to play in. Are there others out here in CA who have bought and successfully registered out of state trials bikes to use on public/ohv land? I know about the red sticker nonsense, but I would like to be able to use the bike at least red sticker months. Thanks for any input.
