Don't forget Beringer as 'dims' are same & you're more likely to find access to them in Endurance than you are the above mentioned. Beautiful things, but tend to be wide mouth as all true Endurance calipers are. Word of caution, endurance pads are thicker than standard and if you fit Endurance calipers you must have pads. On your standard bike you'll end up with needing to re-engineer from the yokes down if you want the discs to sit central in the calipers, or run part worn pads on the outside of the caliper to compensate and then you'll expose the inside pistons too a lot more crud than you're used to! Seal sourcing will be essential and these aren't available from Brembo at all, also the deeper nature of thse calipers could lead to contact with the wheel itself. Caveat Emptor!
