The weather in Singapore is the reason.
Plus the number of stops in Singapore....dont justify for it.
And plus....full armour does not mean your bones wont break or your
life is secure.
It just means less injuries from abrasions.
A full face helmet, thick jeans, covered shoes & thick jacket
will work well enough in Singapore.
edited to add: Plus, your defensive riding and mindset to ride safe
is more important then wearing any armour. If you speed, cut other
vehicles way dangerously or arent paying attention to your
surroundings and the road....no amount of armour can protect you
from an accident.
there has been instances of riders, with full armour, on a heavy
big bike, running into back of lorries in Malaysia at full speed
and died.
There has been instances of riders, with full armour, on sport
bikes, riding fast speed on track, met with accidents, fly thru the
air, landed on the speedway, nearly broke his spine, broke his
hands and some parts of his leg. No abrasions. But certainly broken
bones and nearly paralysed or broken necks.
