Steering Damper Kit
This conversion kit contains all the necessary parts to fit a hydraulic steering damper to 1971 and later Commando models. The damper can be fitted to earlier models but it will be necessary to provide for attachment to the earlier type lower fork yoke and coil bracket in these circumstances. This conversion kit was not installed on production models at the factory, but was offered as an after sales option to suit certain operating conditions.


1. Release the two large knurled knobs and lift the seat clear.
2. Remove the fuse from the battery negative lead.
3. Turn off the fuel, disconnect the fuel lines at the taps, remove the fuel tank securing hardware and lift the tank away.
4. For ease of handling at a later stage, the left side ignition coil can be removed, though this is not essential.
5. Remove the coil bracket-to-frame left hand rear bolt to allow fitting of extended stud 06-4611. See Ill. 2.
