I believe the first production model road fork, with a spring in one leg, and a damper rod in the other, was the Marzocchi M1R, fitted to some Laverda's and the Ducati Paso. Maybe even to the Bimota DB1, I'm a bit vague on that fitment, though. Must consult Google.com sometime, for clarification purposes.So tell me then Walter, how do you explaIn forks that have damping in one leg and sprung from the other?
From memory, the M1R fork had far larger tubes than 70's road bikes, and a bit fatter axle and secure fork leg axle clamping. The effects of the imbalance of springing and dampening between each fork leg would have been kept in check by that very rigidity.
Danger, is my business."
