I am a rad guard believer. Some years ago I stepped off my WR426 in the Victorian high country ie small hills compared with the Rockies et al. But the Vic country is rough in places, and the 426 did a big endo in the rocks and bent the right radiator into weirdness. But it didn't leak, which was even weirder, considering.
So now, with my WR-R being a dollar earner, a Force guard went on first thing. Will it work? F*** knows. Hope like hell I don't have to test it. Going on current form, it could happen! The only thing is that the Safari tank bumps into the rear mounting bolt, but is ok so far...
