I talked to an Ohlins US rep and was told there is no setup made for the IS-F yet. I do know FIGS is working on that
It looks like Ohlins Japan maybe be doing their own build to order setups. If you check the specs, they offer 12/10 spring rates for the is250 and is350 and 14/10 for the is-f. I followed FIGS suggestion and ordered mine with 16/12 spring rates.
