The front/endbell are closed; but there are various mounting-holes for the screws in the frontbell, and that's enought to let sand in, which sands off the first layers of the kevlar. if you don't act early enought (sealing the holes wich are not used, sealing the kevlar-fibres with super glue), the magnets get loose.

I didn't believe what I saw when I opended the motor the first time, lots of sand, damaged bearing, damaged kevlar. Even though I keep my car clean inside!
