Fastener Torque Specifications
Correct tightening torque of threaded fasteners is very important to your safety. Always tighten fasteners to the correct torque. In case of
a conflict between the instructions in this manual and information provided by a component manufacturer, consult with your dealer or the
manufacturer’s customer service representative for clarification. Bolts that are too tight can stretch and deform. Bolts that are too loose can
move and fatigue. Either mistake can lead to a sudden failure of the bolt.
Always use a correctly calibrated torque wrench to tighten critical fasteners on your bike. Carefully follow the torque wrench manufacturer’s
instructions on the correct way to set and use the torque wrench for accurate results.
