Rizoma Ducati Diavel Front Fork Slider One of the first parts of a motorcycle to contact the road in case of a fall are the front forks and swing arm, and repairing them can often be a heavy or even prohibitive expense. RIZOMA guards are designed to protect the fork and swing arm in case of falls, preventing them from scraping on the ground and softening impact stress. Their elegant design adds to the overall style of your bike.
