Anyone swapped motorcycle engines into Classic Vespas? My impression is that such a swap would be far more difficult than for a Lambretta. Which of course doesn't mean it hasn't been done.

I remember seeing a Vespa PX with an H2 engine it. The engine was pretty much on the floorboards. H2 was a 750 triple two stroke. I wonder if the owner is still alive?

Was this chassis built up from a Vespa front with sheet metal and tubing welded up to hold tank, seat, and engine?

Yes. Think it's done by someone in Barnsley ? He used to sell (or still does ?) a fibreglass back end which would then fit over the tube frame, from a few yards away you wouldn't know the difference.

having built a bike engined lambretta i can understand why you would want to do this, lambretta innovations built a rotax vespa a while back, very well done, i belive its a rotax kart engine, all mounted on one swinging arm, centrifugal clutch so you ride it like an auto, i think its been clocked at 100mph, heres a couple of pics.
