Are there any monkey bikes light enough to lift into a trunk?

I'm thinking about a monkey bike, but they're SO HEAVY. I remember the old 90cc two strokers could be picked up and put in the trunk of a sedan pretty easily. Some of these weigh more than full sized 250cc dual sports.

I want to be able to lift it in and out of the rear hatch on my Jeep Wrangler, without needing a ramp. I want bigger than 50cc, but other than that I'm open to possibilities. Is there anything out there that fits the bill?

Watching closely. I have a whole thread on this recently. Came to a conclusion , but my requirements were just a little heavier/faster/bigger. But not by much
