UFO Superbike Front Fender

Installing the UFO Superbike front fender in combination with my SuperBrace involved, basically, just cutting the fender to accomodate the brace. The fender needs to be cut in two places -- the walls of the fender need to be cut to enable the brace to pass through it, and the winglets that wrap around the forks need to be trimmed because they now need to wrap around the brace. (As of August '02, the winglets on UFO Superbike fenders are apparently too narrow for a KLRs forks, and need to be trimmed similarly to what's shown on this page even if you don't have a fork brace.)

The cross-section of the SuperBrace where it passes through the fender is smaller than the largest cross-section, so the hole you cut through the fender need not accomodate the SuperBrace at its widest point. I found it convenient to cut a larger hole, though -- this makes it easier to fine-tune the position of the fender once it's on the bike, and when the fender is mounted it doesn't show much one way or the other. For purposes of fine-tuning the position of the fender, it's also helpful to slightly oval or just enlarge the mounting-bracket-mounting holes. Since the brace restricts how much you can move the brackets on the forks, it helps to be able to move the fender relative to the brackets.

I'm not a particularly neat hand with a Dremel tool, but fortunately the only part where the results of the trimming are visible once the fender is mounted is the winglets, and those are easy to trim neatly.

I should note that after having gone to all this trouble (what little it was) of modifying the fender, I discovered that it didn't make much difference in handling. At highway speed the bike is a touch more stable, about as much more as might be caused by the difference between 28 and 33 psi in the rear tire. People without fork braces have noticed a much bigger improvement in handling from the low fender. Still, the low fender is better suited to my use of the bike than is the stock fender.
