Anyone know what the radiator material on a 2014 SuperDuke 1290 R is made of? Steel, aluminium, or ?

Radiator has developed a pinhole leak on the backside upper left part of the radiator. Since BikeBandit lists a new radiator for about $542, I'd take my chance to try repairing it myself.

Bike is already out of warranty. The shop I purchased the bike from has stopped carrying KTM.
