NOTE:  The final shaft drive ratio was changed by Honda from 48/56 to 43/50 on the K7 model onwards, (we think!).  Please ensure when ordering you specify which year model you have to ensure the correct drive gear is supplied.  Or better still check which drive ratio you have and let us know when ordering.
