Hi. I wish to replace the original 80mm speedo on my 1976 T3 (Customised!) with an aftermarket cable-drive 60mm one. Could anyone tell me the ratio? Mine has the original manufacturer's sticker, but it's so old and faded that I can't decypher it.
Cheers Chris.

A far as I know all early Veglia (Vague Liar)have a ratio of 1 revolution per metre which is what the sticker should say.
Not sure about the later type.
Also depends on your speedo drive as well, as some models have different types,have a read in Guzzology there is some info.

Thanks Brett. You're absolutely right! The readable part of the sticker on my speedo says 1610 per ****something! So as there are 1609 metres in a mile that's near enough.

My brain hurts! :? If one revolution of my rear wheel is 2.0metres (Near as) that means there are 2 revolutions of the speedo drive per one revolution of the wheel.

Hence a ratio of 2 to 1. Right?

Cheers Chris.
