After searching high and low for a small and simple speedo that read 80 - 100 mph it was finally found!
With a bit of research it was NOS and came from a few possible Italian small bikes dated around 1964 - 1969. Cool and vintage! Yet after more research, speedo gear ratios where to be thought of, trying to match a true reading drive, then getting it. Was a nightmare! So after two weeks of that Mackenzie realised that the corresponding drive would never be able to fit the front wheel. So two weeks of endless research and a great speedo for nothing. Digital it was .. .
However not all is lost, a neat little KOSO speedo has been found and purchased. Although not as cool as the vintage CEV, its not a point of disgust!
