Try Pier City Cycles. They have customised many a Rninet and may have forks left over from , say , a Ohlins converted bike. Email is best way to get them they are often in the workshop away from the phones.
I’m curious, why are you after forks?
I’ve got a Scrambler and still fucking with the dampening screw and preload on the standard back shock. There’s no adjustment on the forks. Was looking at the Ohlins NIX cartridges and Wilbers/ Ohlins for rear.
I’m tight though and still messing with handlebar risers and preload on back.
I do get the argument that it’s a raw, retro scoot and I’ll ride around if I can.
Ffs, I have a Harley too!! lol
