calculate the speed

I made speed calculator for YBR125. Please enable Javascript on your browser
to calculate this, and sorry to w3m/lynx user.

speed calculator

This calculator use the gear ratio of YBR125(5VL), and you cannot use for
Gladiator/FAZER/YBA125. Tyre size is calculated for the standard formula.
The blue letters are for original YBR125(5VL).

speed:km/h

                speed:miles/h


The fact is it isn't correct because the speed is influenced by the air
resistance, slipping clutch, abrasion of tyre and so on.
