Hi Steven,

Until a Tec guru comes up with the figures can I simply suggest you get out on a straight piece of road with a GPS taped to the tank. In each gear hold a steady speed & note the two readings... you'll now have said ratios.

Your speed will be (likely) more accurate than the original speedo gave, and best, independent of tyre size.

Sometimes it is printed on the back of the clock.
