Max and Finn are both right.
$300usd plus freight. Still a lot cheaper than a single cartridge from Marzocchi (if you could get one)
Could have a wheel spacer made and a disc adapter, plus the lower triple clamp area on the stanchion needs to be about 3mm smaller in diameter, otherwise axle and top clamp are correct size.
I want to keep the ABS so will go with the cartridge replacement instead and see how that works.
Just a question for those who have played with the OEM forks, has anyone ever fitted 2 OEM right hand side rebound cartridges to the OEM forks and see how they worked?
