Our rear disc protector is the first design to maximize performance using the stock mounting tab. Features return memory system to absorb heavy impact and not snap the tab off like other heavy aluminum protectors do. This disc protector is the only design to give side as well as frontal impact protection against rocks and debris. The only disc protector that will not add sprung weight to the rear wheel. Induction slots move air flow and have been race tested to improve air cooling to the rear disc. Worldwide patent.
