With a Lambretta Series III/GP weighing in at 125kg and a Vespa GL/Sprint weighing just 90kg thats a difference of 35kg 0r 5 stone, how much power would the Lambretta need to have the same performance as a 25 bhp Vespa?

yes i did,but its an interesting topic that many dont understand too well,
its one thing to compare the power to weight ratio of two scooters ,but can be another once rider weight/laden weight is factored in to the equation .
try the sums again with say an 8 stone rider and a 16 stone rider on each machine...

Some of the terrible hand beaten Asian one's probably come close.

I had an interesting chat with Tony in the Bird in Hand a while back. He didn't look 8 stone. 9.5 to 10 would be my guess
