After several rides on typical Oregon winter gravel roads, I decided to drop the Rallyeform and have a look. I was please, everything was nice and clean. Most of the dirt on the pipes was on there when I mounted the plate. Very little crud was in the bottom of the plate, which was never the case with the BMW Enduro plate. I suspect a lot of that is from the MachineArtMoto Avant I'm running on this bike though. Anyway, all good. Here's some pics. You can see on the left hand side where the pipe is getting hit with dirty water dripping off the crash bar. For an idea of what our roads leave on the bike, here's the dried on road gravy from a single ride.
