-What if it rains?
-What if you own an expensive helmet?
I still remember quite some time ago at Orchard, I saw this 'ang moh' lock his Arai KR RR3 to his Ducati 916. When I went back to get my bike, all I saw left was the strap and the lock....... Bloody thieves.......
u haf to assess the risk that place ur bike is parked at lor,practise common sense.
anyway,if rain,juz walk back and get the helmet if u want,mine is sitting on the backrest,so raining oso nvm..
as for expensive helmet,depends on how u look at it lor,mine is an Arai,but 2 yrs old liao,not mint looking,so far so good.
