Like an asphalt racer or something to use in the dirt with some clearance?
I'm racking my brain right now, I was somewhere recently and a guy had a pile of stuff and had a frame with the steering, pedals and the rear was set up with coil-overs that supported a swing arm platform for the motor to sit on, short chain to a solid mounted rear sprocket axle. Looked like a slightly smaller Honda Odyssey kind of frame with a driver's cage. If I can remember where I saw it, I'll see if I can get in contact.......
