The above is the transmission ratio chart you get in the Rotax Operators manual, but with an extra column I've calculated and added.

The extra column tells you what speed you will be travelling at when achieving 13,500rpm on the stated TR, running Vega SL6 tire at pressures between 0psi and 30psi.

Example: If you were running a 13 on the crank and 81 on the rear, you would be travelling at 70.4mph when you reach 13,500mph (assuming you were running Vega SL6's at a sensible pressure)

Note: The decimal place is not arbitrary, I've calculated these figures to that specific level of accuracy. It's reliant on the circumference of the rear wheel, hence the specification of the wheel type/pressure.
