Edited Date/Time:
Are current KTM OEM hubs forged or cast. Their sales literature states they are "CNC milled" but that's all they say. I didn't think you could mill cast on a CNC and get the polished finish they have so I've assumed they're forged. Not sure I'm correct after looking at the unpolished outer hub on my bike.
TIA

They look like they are cast like other OEM hubs but then finish machined on some of the surfaces.

not 100% on this as I've been out of the loop for a while, but if they are anything like the were a few years ago, they are cast aluminum that is then machined to get that finish on the inside. The right term would be "turned" though, not milled, as it would be done on a lathe, not a mill. Of course there are some operations that require milling on it. My best guess is that they are done on a live tool lathe.

Forging and milling are not the same thing. And technically every hub is CNC machined to some degree. The flange where the sprocket mounts onto, the points where rotor mount, the mounting holes and spoke holes. All that stuff is CNC machined. So you could say that they are CNC machined but it would be kind of a gimmick

But more importantly...In 1972, a crack commando unit was sent to prison by a military court for a crime they didn't commit. These men promptly escaped from a maximum security stockade to the Los Angeles underground. Today, still wanted by the government they survive as soldiers of fortune. If you have a problem, if no one else can help, and if you can find them....maybe you can hire The A-Team.
