Bang for your buck : Showa adjustable forks from a Monster or an SS. The SS is a tiny bit shorter but totally usable . Any model that uses your same wheel and brakes so it’s a bolt on. Then you buy GSXR 01-04 fork legs ( upside down) and swap in all of the internals except springs. These differ from the Ducati internals , larger cartridges, larger rods, and totally separate compression and rebound circuits . You then need to buy Racetech springs for Ducati forks as the GSXR springs are too large in diameter and won’t fit in the tubes.
I also used the GSXR adjusters. There are threads on this conversion on Ducati.ms.
You can usually get a decent rebuildable set of Showas for about $250, The GSXR fork legs might cost $50-150 ( I found a wrecked set with good guts cheap) and RaceTech straight rate springs were about $100/ pr. You end up with a very nice set of forks , sprung for your weight, with improved damping and adjustment, for under $500.
You can recoup some of that selling your leftover forks and stuff if you want.
There are a more installation details , read the posts and decide.
I think you will be very pleased with the results and you can’t beat it at that price.
