Speedometer drive ratio?

I want to get a small speedo and they come in either a 1:1 or a 2:1 ratio (there is also a 2240:60, but I think thats deffinately HD only)

Can anyone tell me what the speedo ratio is?

I have a 2005 speedmaster by the way.

Thanks

your bonny is 2240:60?

hmmm, if its front wheel driven like the S/M I would assume they are the same.

but would like to know as I hate to return anything that doesn't fit (I usually just throw em away).

do I hear a second on the ratio?:D

As the 'burner guy said, 2240.60 for the Bonnevilles. It's a generic UJM ratio that is fairly easy to find, Mikes XS springs to mind. As for sizes, I think that the Town Hall clock would be smaller than a stock Speedy item.[
