MV Agusta Mini Bike from the 70's

Ran across this and thought you guys would be interested. You may know already that MV Agusta built a 50cc minibike model in the mid-1970s. (It's not a foldaway bike, nor for road use). As I understand it, the MV Agusta factory in Gallarate, Italy built a one-off children's replica of an MV Agusta grand prix bike, for their world champion Phil Read to present to his son. The bike attracted so much attention, they started producing them - though nobody seems too sure exactly when, or how many. Mid-1970s, and a couple of thousand units is what I've heard. The bike has a 47.6cc Franco Morini, single-cylinder, two-stroke engine with a variator transmission, and was produced in 8-inch and 10-inch wheel versions. I'm told they also built a 12-inch wheel version with a four-speed gearbox and a proper clutch.
