Review on Enhance Steering Stability: Universal 31mm Aluminum Steering Damper Fork Mounting Bracket for Motorcycle Bike Modification by Imran Roach

The frame I put it on is 2" in diameter, and 50mm isn't even close. It measured from 48.88mm to 49.3mm depending on where you measured around the hole. I'm lucky to have the equipment to solve this problem. However, if you don't have a drill and sandpaper on a 1/2" wooden dowel, this will do it for you. I gave it three stars because I was able to fix the problem and it looks good.
