I installed my Devol radiator guards tonight and I must say, they are pretty cheesey. There is no bracing in the back of them at all, I really dont see what they will protect in a bad crash. To make things worse, my top bolt holding my plastic louver on was real tight so I used a pair of pliers to hold the tab while I loosened the bolt, when the bolt broke loose the pliers jabbed the radiator putting a hole in one of the tubes, small but leaking none the less. I now have my first dab of JB weld on my bike. I will be watching to see what Works and Unibiker come out with.
