I have a Telefix fork brace and I'm not sure what it fits. Looking for some guidance. It is 170mm center to center and has 'A3' cast into it. The size where it clamps onto the forks is 57.5mm. I had a '78 R100/7 and it didn't fit that so I am looking to pass it on to someone who can use it. Hoping someone out there knows what it will fit.
