A bit before my time, there were around when I started to ride, but no new ones, I note tax disk 1959 I was 8 then.
My dad said motor bikes were too dangerous, but he would let me have a scooter, I was not going to point out likely scooter worse or he may have stopped me having one of them.
Started with Honda P50 moped, engine built into rear wheel, top speed around 25 MPH, but said it would do 254 MPG on a level paved road at 16 MPH, it had a 0.6 gallon tank, and it would do 64 miles North to Mid Wales flat out all the way on a tank full.
All Lambretta Scooters were claimed to do 100 MPG or better. Even the 650 Bonnie did 60 MPG, and with carbs no fuel injection back then. Even cars the Reliant and the Citroen 2 cv could do 60 MPG, so what is wrong with the vehicles today, we should be looking at 100 MPG for a small car, what went wrong? Weight and speed I suppose.
