TL n°3

Pit Road Limiter : Calculation

To calculate bike speed and more specially the engine revolution for the “Pit Road

Limiter” parameter, a calculation table is proposed. The picture below is showing a

presentation of this tool.

This tool is attached to this TLn°3.

Pit road limiter is only effective on 1st and 2

gears. Depending of your secondary

reduction ratio, the bike should be run on 1st or 2

to adapt engine revolution to

the situation.
