| There is a school of thought that says that hard back protectors have caused needless neck injuries due to not being tied down enough, moving up in an accident an compacting with the base of the skull.
However I say one fitted into a Ducati jacket would be very comfortable, - and you need to be comfortable on a bike. I did have one of those very large, cover all of your back Knox ones, and was so damn restricted I swear it was dangerous wearing it. I sold it and got a more minimal cLOVER jobs.
Few of the racers, Troy and Edwards that I know of wear chest protectors also. |
