Hi Jandi,
Motorbikes are not that common on the roads in Brunei, they tend to be used more as a leisure activity. Most bikes are mopeds/scooters. There are a couple of Bike Clubs and most members ride Harleys. The standard of driving is not too bad here but the average person speeds, doesn't check mirrors and uses their mobile while driving (even though the law prohibits all).Â
There is certainly no reason why a female shouldn't ride a motorcycle.
I hope this helps
