well , its a shame to say yes i wasnt wearing the helmet but that was least expected!... after 1 hour of intense riding we stoped to relax and my friend said go check my bike, i wasnt wearing helmet and was just chilling.. so i went out just to check it... long story short the over inflated rear wheel locked up preety bad before a corner and tried skiding and sliding which i managed to control after some struggle..but the corner was still there..left no time to respond or lean and banged into foothpath.. btw that place at karachi track we call "Qatil Moorh" as many of our riders had accident at the same spot and some even have passed away!!
Moral of the story ... Wear helmet no matter ure engine is not even running ,... as they say.. ride for the fun and dress for the crash!!
