Important Safety Disclaimer The factory documentation provided here is intended for certified motorcycle technicians, experienced mechanics, and highly skilled DIYers. Working on high-performance enduro, trial, or supermoto bikes involves inherent physical risks and the potential for severe equipment damage if done incorrectly. By using these files, you acknowledge that this technical data is strictly for professional repair reference. Always follow safe workshop practices, use the correct specialized tools, wear protective gear, and take your bike to a qualified shop if you are not fully comfortable with complex jobs like splitting cases or servicing high-pressure nitrogen shocks.
