Bullet Proof Designs Radiator guards are tried and tested by some of the top riders in Enduros, Hare Scrambles and Desert Races all over the world. Our new lightweight (15oz each) design does not adversely affect cooling or restrict air flow. These guards mount to the frame providing top-tier frontal and side impact protection without interfering with fan kits. The all new lower bowl protection and ribbed design gives our guards a strength that is UNMATCHED!
