Anyone parting out a 2nd gen?

I think the bolt pattern is different?

Are they? I was under the impression that they were basically a direct swap

Oh I see.

Yeah, i just read that thread again too. Some conflicting info though still...

This too:. 2016 / 2017 wheel differences

Since I'm running a gen 1 pattern rotor on my gen 2, I can assure you it's a straight bolt on fit. There is a bit of interference with ABS ring - this seems to be where the modification is, but it hasn't affected the ABS in any way.

Any photos mate?

They're 100% different. The PCD for rotor mounting holes is larger (mounting holes are further away) on the 2nd gen compared to 1st gen bikes.

Not true - otherwise I wouldn't have been able to fit a gen1 disk on my gen2. What is different is that the stock gen1 disk is smaller than the gen2, but the upgrade larger disk is a straight bolt on.

I distinctly remember the PCD of the older duke rotors to be around 3inches and the newer ones to be around 4inches when I measured them myself. I'll re-confirm again soon.

Do you mine taking some measurements of your old disk?

Mirius · 2022-09-03T16:12:56-0400

Have to try and find it...

Only if you happen to see it. Otherwise, no big deal.

I also believe the 1st & later Gen. Dukes carry the same bolt spacing
The only difference are the total diametre for the 1st Gen. 300mm, second 320 mm (and the early 1st Gen 200cc is 280 mm)

Galfer has different part numbers for 1st and 2nd gen dukes and mentions they are incompatible with each other.

Both the links below are for 320mm rotors. open these in two tabs, cycle between them and see the difference in PCD.
1st gen : Standard Oversized Floating Wave® Rotor - Front - DF800CWS - KTM 125 Duke ABS 2014-2016, 200 Duke ABS 2014-2016, 390 Duke ABS 2014-2017, RC 390 ABS 2014-2017, RC 390 NON ABS 2014-2017
2nd gen : Standard Floating Wave® Rotor - Front - DF940CW - KTM 390 Duke ABS 2018, RC 390 ABS 2017-2019, RC 390 NON ABS 2017-2019

Galfer does make different disks. They both still fit, so I put practical experience over the data sheet. And yes, in case you wonder, the Galfer part number on the disk fitted to my Gen2 matches the Galfer gen 1 disk.
