Interesting... i didnt know that. I am not trying to offend you but why not get a hemet that protects your ears?
I dont have a problem with all motorcycles just the ones who i have to stop a conversation with my kids when they ride by. These loud bikes aren't loud for saftey they are loud because they want everyone to notice them. Someone reving their motor and driving away from an intersection isnt trying to alert other drivers that they are on the road.
I have a full face helemt, a 3/4 helmet and but I prefer a 1/2 helmet. I don't want to feel closed in when on the bike.
Now in regards to the loud bikes mentioned in the other post I can almost bet they are the RUBs that spend a fortune on their bike making it extra loud so they can annoy people while putting on about 500 miles a year riding around the block.
