    My kids have used up all my innnnernet for the month........I'm on dial up speed.....
    Despite this being Kiwi Biker I'm going to give and intellag.....intellegi.......brainy answer....
    The final drive will have a ratio stamped on it...33/10 or summit.......that should match up with the speedo which has a W*** number at the bottom in small writing.....you may to put your specs on for that....
    Here is a link to all that stuff.

    Good info John .... the speedo and rear drive match up and according to the table the bike is doing 3900 at 100kph but is in fact showing 4400 and overreading by 500rpm so disregard my post at the beginning of this thread.
