Ah…no. The throwout/thrust bearing wears out when the clutch pedal is depressed which engages the clutch. When pedal is all the way there is ZERO wear on bearing.
They freewheeled because they used 2 stroke engines.
On closed throttle overrun the crankcase could get oil starved.
I imagine 2 stroke scooters freewheel for the same reason.
My dad’s old buddy had one of them in the late 50s. He was a character, eccentric in many ways, and brilliant.
