ABS  look up translate image
1. Anti-lock braking system. System that senses when a tire is about to loose traction during braking and decreases braking force, preventing tire lock up. 2. The ABS detects when a wheel is not turning and releases pressure to the brake on that wheel, preventing a skid. 3. A component added to the braking system that detects wheel lock up. The system then modulates the brakes at that point with the idea of stopping you faster than you could yourself.

  • BALLISTIC NYLON  look up translate image
    A specific nylon developed by Dupont for the U.S. Department of Defense for use in flak jackets. Later it was replaced by Kevlar. The basket-weave construction helps add abrasion resistance as opposed to a plain weave. The name is used as a marketing tools with ballistic sounding like something "bulletproof" therefore really tough. May motorcycle apparel companies us the word "Ballistic" when describing material. In many cases the materials tear and abrasion strength does not meet a minimum standard for motorcycle apparel and the word is used only as a sales gimmick.
