These fork protectors (pair) give utmost protection to the fork seals. The principal difference between tight neoprene, and bellows-type protectors is the lack of 'breathing" in and out. Over the life of the motorcycle the summation of the shock seal distance traveled comes from the first few inches, and when this area of the stanchion is kept clean, dust and mud-free, (and bug-free) the seals will have the longest service life. Velcro attachment allows easier installation, no tools are necessary. The Fork Protectors are simply wrapped around the stanchions and the Velcro strap closed. The ends are then attached by cable ties to the sliding tube. 044-2100 is the same but without the velcro closure; even more simple & effective but installation is naturally more complicated.
