After years of building billet parts for their own bikes and quads, the crew at Extreme Engineering has decided to release their own line of custom machined billet accessories. All the pieces come either polished or anodized in black, red or blue. With some new billet pieces that we had never seen before we couldn't wait to accessorize our project 400EX.

This custom billet oil filter cover overlays the stock cover. Just remove the two oil filter bolts, install the cover, and reinstall the two bolts. Couldn't be much simpler and it adds a very custom look to the right side of your 400EX. It is finned to act like a heat sink and draw the heat out.

Now to add some billet to the left side of the 400EX we installed this machine started cover. This piece is designed as a complete replacement and come with sealed bearing installed. Just 4 bolts and you have a trick billet piece to separate your 400EX from the crowd.

Now that we had customized each side we added this smoke lens cover to the front headlights. While you may not want to block any light at night it does add a custom look to your 400EX during the day or when racing.
