GB Racing motorcycle protection kits are engineered and produced using the most advanced CAD design, precision injection molding, and long glass fiber nylon materials. Long glass fiber nylon offers several performance and manufacturing advantages over other commonly chosen crash protection materials — and GB Racing has perfected its use in precision injection molding. The result is a product that offers 10-20 times the strength of traditional materials, and which is highly impact and fracture resistant and fits perfectly over your stock engine covers. GB Racing motorcycle protection kits offer incredible strength and impact protection for a fraction of the cost of other materials — a complete kit is often less expensive than a single piece from another source in a lesser material!
