The right fork for the 1090RR and the 1078 are the same part number: 8B00B2160On 1090rr there is no spacer, the left fork foot is different, at the right it’s the axle that make alignment. So i need to reduce ID from 10mm,
That photo! Fantastic.I don't know anything about your Brutale forks but I had a spacer made to get my 1999 F4 wheels with 35mm ID axle onto my 2013 F4RR Ohins forks that use a 25mm ID axle. There was a lot of trial and error because the axle ID wasn't the only issue. The fork leg spacing, brake rotor position, and bearing lip also played a part. Here was my solution but I have no idea if that will work for your forks.
