HPCorse - Hydroform Black Muffler for KTM Duke 390 - 2017 to 2020

Hydroforming presses stainless steel into a die with high-pressure hydraulic fluid, giving lightweight, seamless, structurally stiff pieces with reduced thinning and enhanced mechanical properties. That is how HP Corse makes the Hydroform, for the KTM Duke 390 (2017 to 2020): 0.5/0.8 mm stainless walls, a black ceramic surface, a removable dB killer in 35 and 40 mm steps, watertight stainless rivets and a laser-engraved logo. It weighs 1,140 g without the dB killer and link pipe. This Duke 390 version is for race use only.
