Setup, Compatibility & Care
Installation of this kit involves disassembling the front fork assembly. It is highly recommended to perform this task in a clean environment to prevent debris contamination inside the fork tubes. Ensure you have the manufacturer's manual for your specific motorcycle model to verify fork bolt torque specifications. Always use high-quality 15W fork oil as specified to ensure the damping valves operate within their designed parameters. Regular maintenance, such as checking for oil seal leaks every season, is crucial for preserving the performance longevity of the kit. If you lack experience with fork internals, professional installation is advised to ensure safety.
