How to reduce engine noise amplified by your skidplate


Red Dog

Since I ride mostly in the desert, I have a aluminum skid plate on my bike. And while it does a great job of protecting the cases from rock damage it reflects a great deal of engine noise.

I read somewhere that placing a piece of foam between the skid plate and the engine would cut down this noise. But at the same time it seems that it could potentially block airflow thereby increasing heat which is not a good thing.

Since I had an old wetsuit that I don't use any more, I cut a piece of rubber from it to the shape of the inside of the skid plate and glued it in place with liquid nails. Anyhow, after the glue dried I bolted it back onto the bike. Since the rubber was only 3mm thick, it didn't cause any fit problems.

When I started my bike, I was blown away by how much less mechanical noise there was. The difference is amazing. :thumbsup: I think all the skid plate manufacturers ought to do this. Similar results can probably be realized with other types of rubber as long as its not too thick to pose potential fitment problems. If you try, this I'm sure you'll agree the results are worth the effort.

      An Adventure Foot Peg with Proven Purpose. 
      A larger platform with better peg traction & much improved comfort .
      The Impact Adventure Peg, Patent # US 6390488, accomplishes this by isolating the large cleat from touching metal to metal, resulting in the rider experiencing less vibration and abuse transferred to the foot. With the Impact Adventure Peg you'll have more leverage, while your foot stays better planted, resulting in your feet, ankles and knees feeling better. This adds up to a better day on the bike.
      How does it perform?
      Proofed out in the notoriously choppy, teeth chattering, West Rim in Southern Utah, a trail that is initially so harsh with slick rock ripples many find an alternate route to the “good stuff.”   This was the perfect proving ground for the Impact Peg, as often riders feet vibrate or bounce off of the pegs from the continual chatter. With the Impact Moto Peg the harshness of the rocks was squelched, the riders feet stayed on the pegs, and brutality of the notorious chop tamed. Further the slick rock drops provided the perfect opportunity to test the how the Impact Moto Peg performed on massive impacts. Our test riders repeatedly launched big rocks to flat landings, noticing none of the sharp pain or sting shooting through their feet to their lower back as they would with any other peg.
      What is the Impact Moto Peg made out of?
      Both the cleat and the base are made out of 7075 T6 aluminum, providing the best structural integrity and wear resistance. The cleat is 112mm long by 60mm wide to provide a large platform with extra leverage often needed on large adventure bikes. 13 5mm Inserts are positioned for optimal traction and wear resistance. The base is shot peened and anodized, while the cleat is hard anodized for wear resistance. The cleat is isolated from touching metal to metal through our base elastomer on the bottom, and cup elastomers on top. 10.9 bolts secure the cleat to the base, making the Impact Moto Peg not only the best performing, but the strongest aluminum peg on the market.
       Models:
      Currently we only offer the Adventure Impact Pegs for KTM Adventure bikes, old chassis KTM/Husqvarnas (pre '16) and Husqvarna 701. We should have Adventure Pegs available for BMW, Triumph, the African Twin and Yamaha's Super Tenere shortly. 
      Features
      Absorbs vibration and abuse. The elastomer absorbs vibration allowing your feet to remain better planted on the pegs. High-frequency abuse like spikes, jolts, and bumps are also dramatically reduced through the cushion of the elastomer. Exceptional traction A combination of our tooth profile coupled with minimized vibration, and larger platform (112mm x 60mm,) literally grabs hold of the bottom of your boot. Hard Anodized 7075 T6 Aluminum Provides exceptional construction, strength and wear resistance. Down and back. The KTM Impact Adventure Peg is a 1/2" down and back to open ergos, providing more room on the bike.
