Many Hondas have used a shock softening device for just the same reasons. In the last of the single cam 750's it was a clever disc in the pack. Being just the same size as two regular discs, many replaced it with two for added "bite" The VT's (V-twins) have an incredible clutch system to soften and civilize the beasts.

In VW Beetles, Gene Berg sold a device that gave a slight cushion to the engagement of a racing clutch to soften the blow. Not just to the crankshaft, but the relatively soft magnesium alloy case as well. You see, the crank is forged, rather than cast, so that it can flex without breaking. A certain amount of flex is required, because of the flexibility of the case. A cast crankshaft would break from the flexing; indeed, even some forged ones do from time to time. It is rare, and the only one I have knowlege of personally, the engine still ran, although with a wierd noise and rhythm. But itran!! Upon teardown, lo and behold: broken crank!
