GBRacing Secondary Engine Covers are manufactured from our High Impact, Reduced wear, Injection Moulded 60% LONG GLASS fibre nylon 6.6 Engineering materials. Extensive research, testing and development has allowed us to create a unique High Quality product range. This process offers greater design flexibility, allowing greatly reduced costs, compared to similar Carbon fibre / Kevlar & Billet Aluminium covers. All our products bolt directly over the existing stock covers, simplifying assembly, negating the need for awkward and difficult to remove adhesives. As an injection moulded process we are able to design optimum asthetics, enhancing the overall look of the engine covers and the bike. Not only do we manufacture Secondary Engine Covers for the Stock covers, we also manufacture some Secondary Engine Covers for the factory Kit covers, normally used on Superbikes. Approved by the MCRCB, FIM & Other Countries Worldwide.
