So it rains around here in the summer like clockwork every single day.
Sure, you can stay inside to avoid the rain, but the roads are still wet, so you still get the skunk stripe on your back from the lack of a decent fender/hugger.
My first try was putting plastic in the split. That didn't work, as the fender is still too skinny. Putting on the top rack kit helps a little.
I attached a vintage universal motocross fender. I used a 12" threaded rod through the hollow axle, and the supports are 1/2" aluminum tube with the ends flattened. I put a small hole in the stock hugger and a bolt through that to fasten the front of the fender.
I painted it flat black to match the swingarm and sidebags. I discovered you can't paint white plastic black and it scratches right off, so I have a real molded-black fender ordered. It's a bit smaller, so it should look a little better.
T'ain't purty, but it works.
Thanks to Preston Petty for inventing the vintage universal motocross fender.
