    Chamber Delete

    Has anyone gotten the competition Werkes chamber delete for their new gen 390? I was thinking of installing it on to my ‘22, but I’m not sure of the O2 sensor location so I don’t know if I would need a piggy back or not.

    Hi Guys, I own a 2014-15 RC390 and looking to put a performance exhaust. I bought a second hand Akrapovic slipon with leo vince mid pipe. The guy I bough it from was using that setup on 2017 RC390, i thought the same setup would go on 2014-15 RC390 but I was wrong. The mid pipe fits the header...

    Need Help Does a cat-delete midpipe require a new ECU and remap? If so, are there any that do not?

    Hello, just what the title says. I have a 2017 and I want to upgrade my suspension. Apparently, the Yamaha R-series rear shock absorbers that are compatible don't fit 2017+ RC390s without deleting the cat. I'm pretty darned ok with the bike's performance on the street and highway, so I really...

    Header Pipe Removal and Tyga WSS300 exhaust installation

    I have removed the mid pipe and the muffler, but I cannot get the header pipe out. It seems stuck in the frame. I have TRex racing frame sliders, and unsure if that's causing the problem or it is just a pain to remove header pipe. Also, I got Tyga WSS300 exhaust, however, the header pipe and...

    New from Houston area 2017 Duke 390

    So I just bought a Duke 390 that has 1500 miles on it. I have owned bikes before. I have ridden dirt bikes since I was 4 and my first motorcycle was a 955i Speed triple, then a vt1100(early model with 20 more hp and 5 gears), then a valkyrie, and now back to a KTM 390. I'm hoping to do a full...

    2014-2016 Mivv "Ghibli" Exhaust and Hanger

    Selling a Mivv Ghibli exhaust which fits 2014-2016 models, may fit later models if you buy an early model header pipe or tyga one, but don't take my word for it. Owned for one year without crashing, selling because it scraped while leaning over at the track last weekend and I don't like that...

    Tyga header length

    How does the tyge header length compare to the stock ktm header? Is it possibly slightly longer? I have a '15 with akra exhaust with both midpipes. The bike came with the catted midpipe attached on the front face of the frame tab with nearly max overlap on the header. The open midpipe...

    2016 CUP BIKE - Tuning Question

    I understand the 2016 Cup bikes use slightly restricted tuning from the factory to approx. 38 bhp. Is it possible with just a power commander/dyno to open up the power a bit on the exact same exhaust? Or would you have to at least remove the cat on that Akropavic to open it up further with a...

    DIY Exhaust Hanger/Mount

    If you are like me, you do not like the current options for exhaust hangers on 2017+ models. The stock mount that is integrated into the right passenger foot peg is ugly in my opinion and leaves you with few options once deleted. One of the few bolt on pieces that I am aware of is from R&G...
