We used the clamp from the Ducati damper. The original damper has a slightly thicker mid section only compared to the Arrow (about 1.5mm). The clamp will not tighten down sufficiently to secure the Arrow damper.
You can do one of two things, wrap about a few turns of aluminum foil tape around the Arrow damper till the clamp is able to secure it when tightened down or file down the section of the clamp where the bolt screws down so that it will tighten down further.
We are sourcing the correct sized clamps that are a bit 'prettier' looking.
