£650 Ducati Performance magnesium yokes. 30mm offset with 53mm / 56mm fork holes to fit Ohlins road forks. Top yoke is in ceramic chromate finish, bottom yoke is in zinc chromate. Excellent condition. Continuing the clear-out and putting this yoke up for sale. I bought it off here back in 2017 (original listing still visible) with the intention of fitting them on my 998S. Never got round to it and they've been sat in a box under my bed since then. As they haven't been fitted they are in the same excellent condition they were in when I bought them. Photos here are from the original listing apart from the final one (boxed).
So, I think they are 30mm offset - this was the measurement from the original listing when I bought them. If you let me know how to measure the offset I’ll get a ruler on them to confirm….
Just re-read your original post and saw you had stated. Sorry. I have no idea how to measure it myself but I’ll pass the ad onto him in case it’s of use to him.
