Ducati are pretty good with mods........so long as there parts are used and there people fit them.
i appreciate the PC or a FIM wouldn't affect the rockers, but if you give them a loophole they could jump straight through the middle of it.
If you've asked and they confirm you'll be OK then you've covered your back.
If you don't and you're handed a bill like Paul could've have got, you'd be pretty pi55ed off
