In CA it really helps to connect trails to roads and makes for great loop options. Camping off a dirt bike is also dreamy.
It can help us get around the green sticker/ red sticker problem too. For example a red sticker WR 2003/04 with a plate can be ridden year round but without it it is only in red sticker season. You can also use a sumo on pavement without taking it to the track. You spend more on insurance and registration but is well worth it to me. I'm on my 3rd plated dirt bike.
This. I'd consider dual registering, but seeing as it would be a red sticker it would just make things confusing with no real benefits.
