Aprilias used P4's you could try them as well. I've seen them go for about £150 on eBay in the past. KTM also list spare parts for P4 calipers whereas Ducati do not
as per - ACU reg 14.22 BRAKES For machines fitted with two front disc brakes, a split of the front brake lines for both front brake calipers must be made at or above the lower fork. So having the split at the lower yoke achieves this.
