Now the fourth motorcycle manufacturer (1, 2, & 3) to issue a recall because of issues with its fitted Brembo brake master cylinder, KTM has the dubious task of informing 2,361 KTM 1290 Super Duke R (2015-2018) and KTM 1290 Super Duke GT (2016-2018) owners.
Like the other recalls before it, this one stems from certain 15mm and 16mm radial-pump brake master cylinders that have been fitted as an OEM part to a slew of high-performance motorcycles.
Because of a manufacturing defect, the plastic piston on these master cylinders – made from a polyphenylene sulphide polymer – may crack and brake under heavy load, severe ABS engagement, and/or during a tip-over.
