Quads that Lean and Strange Machines

We're taking a look at some of the weirdest and most innovate sport ATV concepts in the world:

Yamaha Tesseract and Other Cool Concepts - ATVConnection.com

Reminds me of the Piaggio MP3. One wild machine that's a blast to drive. Push a button when you come to a stop and the machine stiffens up. Don't even have to put your feet down. Take off and it unlocks and ready to lean into corners.

I'm surprised no one else has copied the Can-Am Spyder. The 2 wheels in front I think would make it feel like basically riding a quad. There are a few Chinese knockoffs but they're basically scooters that simply look like it and have nowhere near as much power. And the optional electric shift seems pretty cool too. My local dealer just got a used one in recently, an SE5 model in fact. If they weren't so darn expensive used(asking $10,999) I'd probably buy one.

The Polaris Slingshot belongs in the category of strange machines. Is it a car? Is it a motorcycle? What the heck is it?

It' classified as a motorcycle in my state and the operator is required to have a drivers license and motorcycle endorsement. Polaris Slingshot : 3-Wheel Motorcycle - Reverse Trike

The Slingshot to me looks too much like a small car. I could see having just as much fun in a compact convertible like a used older Mazda Miata and spending a fraction of the money.
