Hi
I want to use a mini speedo on my street fighter build like in the like below.
What's the specs on the original speedo, the link shows this one to be for a 19 inch wheel & 2.1 ratio
Hope some one can help

I THINK the standard Yamaha ratio is 5 to 1. Why not go for a digital unit with a needle indicator? :

Only having a speedo & small neet easy to fit & not much goes wrong with a cable
Looking at this one may do model 2
