Speedymoto. The bolts seem to be of superior quality to the Cyclecat units I see on most 749/999 SBK's. Be sure you have an experienced installer do the cutting. They look like crap if they're not located centrally in the hole and/or if the hole is cut too big. A hole saw 1/4" larger diameter than bobbin should leave a consistent 1/8" gap around perimeter which is nearly invisible. Take care
