Unsupported, a service loop probably would be a problem. I clamped mine with an adel clamp in at least one location. As for the service loop, you need to allow for caliper movement owing to pad wear, so some degree of left/right motion is needed. However, changing pads requires that you move the caliper a fairly long ways inboard, to disengage the large guide pins. If you didn't have a service loop, you'd have to disconnect the hydraulic line. Same thing if you remove a wheel for tire change. I'd put the loop in again. Just watch where the gear fairing can contact the line, I found some chafing there until I readjusted things. The gear fairings like to move.
