Yes, we've come a long way with motorcycle rider training and safety courses. I was digging through The Kneeslider research library and came across this Jawa training motorcycle in an old issue of Cycle. It was powered by a 250cc 2 stroke engine and had complete dual controls. The instructor sits in back and has fully functioning handlebars connected by rods to the front fork with a throttle, front brake lever and clutch. He had a rear brake pedal and footshift for the 4 speed transmission and there was also an ignition cutoff.
That had to be an odd experience for both student and instructor. I wonder how many of these they sold.
