If you are concerned about safety, bring your helmet from home (you mentioned you are getting an IDP so you have a bike license, right?)
You can buy helmets in Bali - varying quality. The good ones are harder to find and expensive.
If you do go with a helmet from Bali, make sure you at least have a face cover as it really, really stings when it rains with an open helmet, not the mention getting hit by bugs.
