Pengarang is nice for riding and you should be in a group of about say 10 and bring spares and stuff like that. It is not the best place to be there and a bike part fails. Trust me I know have see that happen to others we meet there and we end up playing good samaritans. Lucky it is us...if it was some local rowdies... good luck. I would not say it is typically a dangerous place to be but as I always say...never leave your BRAIN at home. If a place there seem dangerous...don't think...just move off. Make sure to have someone going who knows how to work the bikes, also good to go with people who have gone before and know the lay of the land. You can get lost if you are not careful.
