Hey guys, just joined and wanted to post my issue so I can share the results once I get it all worked out.
I had my first service done and now I have about 4,600 miles on my 790 Duke. Today my low oil pressure light kept flickering on and off. After a few miles it stayed on so I pulled over. Didn't see anything immediately wrong. Hoped back on the bike and last few miles home the low pressure oil warning came on and stayed on.
So im scheduled to drop the bike off Wednesday July 3rd. Hopefully I'll get some answers after the holiday weekend. Just thought I'd add the issue and results on here for everyone to know.

Many thanks J.D

Mine is a '19 spec bike, the low oil pressure was apparently caused by the filter, this was changed and apparently all is now ok, no mention of why it caused the problem, something I want investigated and an assurance no top end wear has occurred.

The leak was from the top radiator hose and was leaking from within the wall of the hose, kind of in between the layers, so it would seem a manufacturing problem, as opposed to the seating of the hose. The bike is still with the dealer as apparently there is a 2 week lead on the hose.

Got to admit I got a bit pi**ed with the dealer and after a bit of searching found the email address of KTM Austria's MD, filled him in and then all **** broke loose at KTM UK and the dealer and now they seem to be on the case!

Got a loaner at long last, which in my opinion should have been offered straight away, without me having to kick off!

Update. The dealer found the bike was less than a 1/4th of a court low on oil. So they topped it off and the light went away. They tried to charge me for it but I convinced them that wouldn't be in there best interest. Anyways, yesterday the low oil pressure light came back on. They ordered a new switch and I guess we're gonna try that but I'll show them this thread and mention the filter being an issue for some.
I just want the annoying light gone! I can't see any of my **** gauges cause that low oil pressure warning keeps kicking on and off!

So I'm a little frustrated. I dropped the bike off last Friday morning. The shop had to call KTM all day every day to get a hold of someone to walk them through any other troubleshooting options. I can finally pick the bike up today BUT the issue is still there. KTM suggested changing the oil 4,000 miles early from what the manual suggests. So no solution yet and no help from KTM
