The EBC Kevlar® series has now been renamed NAO series or Non-Asbestos Organic, although we still use the famous Dupont Kevlar® fibre in conjunction with other high tech fibres that have come on the market. The NAO series are a superb all round value-for-money replacement for all levels of motorcycle and are still extremely popular with many riders who prefer the "feel" of organic pads. NAO series are fully TUV tested and KBA certified and conform to the new ECE R90 brake regulations which are about to storm the European market. EBC is at the forefront of this technology and will be the first on the market to offer Reg. 90 approved pads and packaging. Most EBC organic pads have expansion grooves which reduce noise and prevent cracking. The aramid fibre compound with non-ferrous particles helps to prevent surface "scorching" under load.
