A few years ago, I did a major tune up to my KTM 400 including valve adjustment and a skid plate. Afterward, it sounded like the valve train was going to rattle out of the bike. Did I screw something up. Bike started perfect. Did some reading. Guys were complaining that the skid plates were making there bike sound horrible. I finally installed this piece of foam. What a difference. Cut it to size and installed it. What??? The bike sounds normal again. And it keeps mud out of the skid plate. Best product for I put on my bike in years. Really??? a piece of foam- yes a piece of foam!!!
Does a fantastic job of keeping mud and debris out so your bike stays lighter all day. Plus makes clean-up easier. Easy to use because you can cut it large and just squeeze it into whatever hole or gap you wish to protect. Never had to do this, but I suppose worst case, you might have to use a zip tie to keep it in place, depending on your application. Doesn't hold lots of water so it doesn't get heavy, and mud can't penetrate so it keeps all the spaces between skid plate and around brake pedal and shift free of build-up. Never had any problems with it being damaged by heat or causing heat build-up. I believe it actually keeps you're bike running cooler on really muddy days because it actually keeps a layer of air adjacent to the cases as opposed to mud. Over the years I've learned to use it in places that I initially didn't think of, such as the area between the rear shock and carb.
