Nope , due on 2016 models and i doubt they will release the slipper version untill standard stock is cleared , they wont want to de value their own bikes .
If the slipper works ill buy and retro fit to my bike .

concern about the slipper is really over blown. $0.02. I've not experienced any point where I felt it would have been with having. It's only being added to have parity with the Kawasaki... The engine braking is minimal, and you can clutchless shift VERY easily, up or down. Hell even shifting clutchless across neutral has been flawless. The slipper is just a marketing feature, and shouldn't impact a decision on when or if to buy.

I raced Supermoto for a number of years and couldn't imagine racing a single on pavement without a slipper. I was really surprised road racing the RC a couple of weeks ago and finding I didn't really require it. I could bang down 2 gears pretty rapidly and even with stock suspension everything was well behaved.

Good to hear that, from a racer's/tracking perspective.
I've always matched-rev when downshifting anyway, be it four or two wheels I'm driving.
That being said, during upshifts from first to second, my bike sometimes misses 2nd gear. It's the only real annoyance I've encountered thus far on this bike

All RC 390's in Canada and the USA should have a slipper clutch. This was a change to them slightly before any were sold here.

You should have noticed that you have significant engine braking on the road as you would expect of a 4-stroke single. And abrupt down-shifts don't produce a chirp from the rear tire which a 4-stroke single would be prone to do...well that's a slipper clutch in action.

Okay... I've had my rear chirp and skip with hard down shifts. How do we know for sure if it has one or not??

I assure you my 2015 USA spec RC390 does not have a slipper clutch... I have opened the clutch side up to install Chad's Factory Pro shift detent. Conventional clutch found inside.

I concur, no slippers in the 2015 USA RC390.
Got the rear to chatter being ham fisted on the track when hard on the brakes.
Then confirmed that the clutch is a normal clutch when I took the clutch cover off to inspect the crank drive gear nut.
I even took a picture.

Correct, no slipper

Well I emailed this question to them and hopefully will get an answer. You can't tell if you have a slipper clutch by looking at the clutch with a side cover removed and the clutch un-assembled.

Service manual shows a pretty normal looking clutch hub and basket. No ramps or springs.

You cannot possibly replace a shift detent without completely disassembling the clutch and removing the basket.
No slipper.

I believe KTM has implemented the slipper clutch on the sly, if what the Indian moto magazines are to be believed. It's supposedly not an upgrade for existing bikes.

A link to the article that leads you?

Here's a youtube video from India of the slipper clutch on the new Duke 390. So I would suspect if KTM were to offer it here in the states, we won't see it till next year.

These articles from India are from 6-12 months ago when the rumors started that the 2015 bikes would arrive to the US with a slipper. It never happened. No new information since then even from the indian press. No slipper on the 2015. The internet speculators now say 2016. You should probably wait till next year...
