A bit of a poser?

[snakey]

I have a 750 sport as well as my Monster, the sport has 16 inch rims and i have eventually found tires to fit it, they are Avon Azzaros, these are a lot higher profile than the original Michelin's making the outside diameter of the tire the same as the monster, my problem is the speedo drive on the sport has packed up and being meant for the original tire size probably would not be very accurate with the higher profile tires fitted, I cannot get hold of an original one but can get one for a 17 inch wheel, which measuring the monster tires is the same outside diameter as the new tires that are on the sport. to my thinking, I should be able to fit the available speedo drive to the smaller rimmed wheel and get a relatively accurate speed reading , or is there something else that i should be taking into consideration that I've missed - the overall outside diameter on both tires is approximately 23 inches

any thoughts would be welcome
