Big note on Red Racing Parts I ordered this screen and a Domino choke lever assembly from them on March 23rd 2016, and they charged me for the pleasure. Today it is May 26th (65 days later) I regularly email these guys about my order--I still have not received any shipments from them! Their...

Just bought a high pressure radiator cap to put on my rc390 cup bike without checking what it came with, turns out it's 1.4 BAR. Does anyone know if this is stock or cup only? Thanks!

Hey guys, I'm hoping to put some number plates on the stock rear seat but am a bit concerned with the material. Do vinyl stickers actually stick to the seat material? It looks like Ari over at motorcyclist.com was able to make their number plates stick: Thanks guys for any suggestions...

Does anybody know where I can buy a set of BLACK fairings? I want to keep my stock ones white so I can change them out when I get bored of the look.

The stock RC390 chain is endless ( no master link) . I got a smaller rear sprocket to give more top speed. I also ordered a Ktm master link for the chain so I could take out a few links and still use the stock chain. Sadly, the master link KTM supplied won't work with the stock chain. Moral of...

The last two times that I've taken my bike out, I've been getting a lot of backfire/popping from the exhaust. It's usually when I'm getting off the freeway and rev matching/downshifting, not really when I just ride around the city. It's never done this before and the bike is completely stock in...

If anyone is looking to buy a RC390 in the SoCal area, 3 Brothers Racing is a good place to start. I bought my bike brand new on the 28th last month. I went to 3 dealerships with $5800 OTD being my offer. Two were "willing to work" with me after they "spoke with their manager." Then I found 3...

I know it is not an RC...but it is time for spring cleaning - I have a white 2015 KTM Duke 390 with only 798 miles. I bought the bike new in March 2015 out of the crate (first one delivered to my dealer) and obviously have not ridden it much. The bike is basically stock except the following two...

I have a few stock parts for sale. Have head light assembly, windscreen, mirrors, rear fender. I can get pictures of everything when I get off work today. Will also have stock belly pan and tail for sale soon, and hopefully depending if woodcraft gets done soon enough I may have stock rear sets...

Ok, starting thread "AGAIN" about RC8R shock on 390. I had this all written up with all the data this morning and went to add photos which locked up browser and apparently because it is a new thread no auto save so here is the short version. It will fit. It is 10mm shorter, does not have...

Hi guys, as I've posted before, I have an insane and unhealthy obsession of grafting a twin disc setup into any bike I own. To that avail I want to swap out the wheels of my RC with those of either an Aprilia RS250 or an older generation Ducati. I believe either combination will be lighter than...

This is what i took out of my Rc390 One stock KTM air intake. Witch i will note is one of the worst air intake systems i have ever seen. Pulling air from the back of the bike all the way to the front. And replaced it with a K&N Rc 9630. I used a 2.25 to 2.5 reducer to go from the intake to the...

Just like the title said. I scraped and cracked my stock right one and want to replace it while I wait for rear sets. Im in Californa thanks! I used one of my rear passenger pegs and its was "close" but the angle is just slightly off. thanks!

Hi guys, I'm planning on designing an exhaust system for the 390 series bikes. My goals are to : - 1) reduce weight. 2) make sure that the power/torque does not change for the worse. 3) Maintain the stock mounting positions. 4) reduce heat emission from the exhaust to the rear shock. I was...

Had a little time to make a proto type piece here to verify fitment and check operation. I am using Frank's captive spacers in the front wheel. Please give me some feedback and or interest in it so I can get a price on having some CNC'ed. Works very well, just loosen pinch bolts and axle and...

I'm picking up my 2016 RC390 in a few weeks. I know that I will be upgrading the suspension. I've had premium suspensions on several bikes in the past. I usually get overwhelmed by the endless possibilities for adjustments (analysis paralysis).... I ride about 50/50 street/track. I don't race...

Ok, the stock grips imho are garbage. The stock factory grips on the mx bikes are great. What are you running and/or suggestions on what to use. Thanks so much.

Just finished this 'light' build. Same bike in both graphs. Bike configuration is; stock exhaust, K&N filter, open lid, with a PCV. The blue curves are the stock engine, with before mentioned external mods, tuned. The green curves are with thin gaskets installed, head porting, valve touch up...
