Torque specifications
Notes from the manual (2)
- Engine-only torque values from the KEL800 workshop manual. Bike-level chassis torques are provided separately in the LX800-2 chassis workshop manual.
- Multiple torque-to-yield procedures use 'starting torque + angle' - read the notes column carefully.
