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.
