yeap nothing under the sit !!! made me wonder ! the sit was in position locked too. maybe seen it was not an expensive helmet the ring could have been pulled out! but not a trace, real mystery. I live in Indonesia since 11 years and i had nothing stolen so far, the locals are not fan of 250cc they are hard to sale so they dont really steal them either, thank god, they love scooters tho. But if a thief get cut in this country people enjoy kicking the hell out of them, if they re lucky the police come around to save them! i ve seen it happen once, people in the street started calling : thief thief, the guy got beaten by several people and lucky for him a soldier going home stopped the mob and arrested him.
