Were they Competitive? The caption on the pic was that a 180cc Vespa won the Junior class.....
Their engines were disc valve were they not? Possibly they could have been tuned to go hard. Couldn't they?

More than just Vespa's, but looks like at least in the UK, scooter racing had some support.

I don't know about racing Vespas, but a couple of factory Lambrettas got here about 1950 and wrought havoc in the 125 class once the Hinton brothers had converted them to alcohol fuel and a ferocious 24:1 compression; the Two Wheels story is reprinted in this forum thread: http://www.forums.il....php?f=4&t=1042
Vespa engines are conventional piston-port two strokes. They can take a fair bit of tuning but the handling is still pretty evil! The Lambretta would have appealled because the engine is centred in a tube steel frame, making it much more predictable in corners.
