i was shocked when
i read 125cc at 249.76 km/h
so i think i should share my research with all pakwheelers
that don't do any thing stupid with your engines
in the name of tuning, to get that speed
first of all those bikes are specially designed for tracks
even legally not allowed on roads
and 2nd the most important thing is that
here we are discussing
GS150 top speed and its a 4 stroke bike
Aprilia 125cc at 249.76 km/h RS125R was 2 stroke bike
and still its a 2 stoke bike
if you have time then visit these links
its a healthy knowledge for all of us
