Yes, in car- and motorbike races. That's because these engines has much more hp, and need a 1/4 to give an ideal performance, and idea of power.
In scooter-sprinting the 90% most often used sprint track is 150 m.
Small 70-80 stroke engines perform the best from 0-120 so the last meters arent realy useful without big gears or sprinting bikes that also perform well at high speed.
In UK and most other countries having the 1/4 mile strip they ride 4 stroke. 4 stroke has a total different powerband than the 2 stroke engines. 2 stroke perform real good in acceleration, and 4 stroke perform better at high speed, in general.
