Sorry,
On the Japanese Yoshimura website under KTM it shows 6 models non of which is an RC390.
I have no idea what the US website is, it also states: "Made in the USA"?
Perhaps it is a partnership doing different brands and models?

From the research and videos that I saw on YouTube and websites that I visited it seems as the 390 Duke RC version never made it to the United states

My goal is to make this pipe work on the standard Duke 390

I think the best way to resolve this issue would be for somebody who has the rc390 2015 or 2017 to measure their header length width diameter to see if I can compare it to my 2015 header

If the headers are the same I could order the remaining parts that I do not have in order to mount and attach the exhaust

The closest KTM dealership to me is over 4 hours away and I asked them if they had any of the headers in stock that would go on this bike and they did not they would have to order it and then if it did not work or fit that would be 8 hours of driving for nothing

Hey T.D.P have you looked at mnnthbx.com? They have Yoshi cans on their site and are at least on the same continent as you.... s.e. US I think? They'll have a wealth of knowledge from what I can tell.

Ive been looking at other stuff for my bike... It seems I have to specificallly search for 2013-2016 us version to find stuff I need. Here is an example.


And after an excessive unreasonable amount of research, The US version of the 390 DUKE year 2013-2016 is the same as the RC390 Duke 2014-2015 when it comes to exhaust mounting / types / use

In order to used slip on style exhaust you will need a Silencer Bracket as well


I hope no one else has to endure this struggle.

Please allow me to quote a part of your initial post:
"I am use to having a bike that makes a little bit more noise and I really like the sound of the Yoshimura R77 3QTR. I have a few questions though"

Your endured struggle is nothing but self-inflicted and I bet the majority of bikers actually find this a large enjoyment part of owning and modifying their bike.

It is a constant development 'educating' manufacturers in our bikes as I have found over the past nine years riding Dukes.
Today, again, I have received the following email from Bitubo, Italy:
"Thank you for your email
May I kindly ask you if you can send us the copy of the vehicle booklet? We don’t have your bike in our catalogue and we would like to check the type code"

So there are two approaches to this, either I start a rant on how incapable the International renowned Bitubo suspension factory is or for that matter KTM on this forum, or I provide them with the information for all future small Duke/RC riders to benefit from this effortless email to them.

I say both, sometimes a little drama gets much needed attention.

As for the self inflicted struggle, I didn't know it would hurt this much... After all its a 2015... That should be more than enough time for manufacture to find out about the bike.

After a few more hours of research I have finally committed to purchasing the parts and they are on order now.


I'll post before and after pictures so anyone in my situation has a good idea of how they can accomplish a custom exhaust set up with this bike

So far the purchase list:
Tidy Fender us version
rapid bike Evo e c u
Yoshimura r77 exhaust and Cat delete mid pipe
exhaust bracket
Totaling 1150 USD

still to purchase
orange underglow lighting for night riding
less offensive and nerdy side mirrors

I recently got a 2015 Duke 390 Second hand and I have to say after owning a few EX250R's that I am hands down loving the bike. Getting it was pure ** show however, Driving it home through the snow / rain 10K elevations down pouring like **.

I am use to having a bike that makes a little bit more noise and I really like the sound of the Yoshimura R77 3QTR. I have a few questions though

If I were to pick up this pipe and attach it, Is it possible I could tune the bike my self?
If it can be tuned my self, what sort of equipment would I need?

What do you guys recommend for aftermarket rear fender? This thing is hideous!

I will be riding the bike sometimes at night, Looking for maybe a possible orange or white under glow for a bit more visibility, Has anyone done this or recommend any ideas

I have read a few times there is options to remove the cat / silencer ? Are parts required to do this ?
Get the powertronics piggyback ECU, Download their R Tune software. Powertronics will provide you with maps with an exhaust and air filter or either one. Exhaust maps are common for all brands if it's only a slip on, for a full system they have the option to select the exhaust you have and then the software will take care of the rest once you flash it.

Once you flash it. And there in lies the issue with the PowerTronics platform. It’s great if you want to play about with maps. Especially if your setup isn’t on that option list. Being Apple based without a laptop and it becomes more effort that I want when I can just plug in the Evo and let it do all of that. FuelX is a big step forward for PT and long overdue.

True,
But broadly speaking, powertronics website has readymade map for a stock, one with air filter, with exhaust and with both. Until you have certain knowledge of manual tuning you won't even serious to change the numbers as it seems quite baffling for someone seeing it 1st time.
And definitely FuelX certainly supported the top end extra punch which was unlocked by the powertronics. Before installing the fuelx I use to never push the bike above 10.5/11k RPM although I had room till 12.5 because it just felt unnecessary and a upshift would be better for acceleration, after installing the FuelX the post 10. 5k band feels so natural man that it seems KTM made it that way and the engine didn't feel it's crying at those revs and it's a place it can be in, bump fuelx to mode 10, it becomes a fucking wheelie monster sometimes at 2nd gear also. That modulated fuel from the fuelx is synced with the ignition timing and TPS by the piggyback. And powertronics controls a lot more sensors, almost everything related to the engine I guess.
INFACT I TRIED RUNNED IT STOCK ONLY WITH FUELX, IT WAS DISSAPOINTING. Maybe barely some smoothness at low revs and that extra vibration at 5/6k rpm was less, rest didn't feel much performance increase as such unlike the powertronics.
