I've bought PUIG lowering kit, 40mm. now i sit pretty comfortable (1.98cm). however this raise another issue. the brake pedal become too high, even in the lowest configuration. had to cut it in half and weld it a bit lower, still not perfect but at least i dont need to raise my leg to use the brakes.
The reference for the adapter is this: 20241N
then you can buy whatever extension size and footpegs from the brand you want, i've bought the touring ones
