We develop our rad guards to thrive in the toughest off road environments. Our Unabiker CRF450L rad guards brings serious protection to Honda's dual sport weapon. We use 2 solid aluminum support rods across the face of the radiators and another solid rod across the back to provide outstanding side impact protection and excellent bracing. Our famous Unabiker swoops provide excellent air flow while stopping trail trash from getting into your radiators. All this is tied together with reinforcing side plates to help strengthen the outer edge of your radiators. All this top level protection fits underneath the stock plastic with no trimming required and is compatible with the stock cooling fan and horn.
