low

New rider and I’m out of my element when it comes to bike issues. I recently did my first service on my 2015 RC 390, I used 1.75l of oil and changed the filter. Ever since my first service my low oil pressure light keeps coming on but only when the bike is up to temperature. I didn’t have this...

Hello all, this is my first post and am very grateful for any knowledge that you can pass on! About 3 weeks ago I noticed my low beam headlight stopped working but I didn't worry about it too much until now. I bought a new headlight thinking that for some reason the stock one went out, didn't...

I am sure this option has been out for a while but I have finally found a source to get the SBS DC compound for our 390's! This is the ulimate brake pad for aggressive track use. Straight from the highest level racers around the world. The upgrade choice for Superbike, Supersport and...

It seems like on the 2015 and 2016 bikes, there were LED kits and lots of interest in getting our bikes to have both headlights on. Is there a reason why people aren't doing this anymore? Does running the high beam with the low kill the battery over time? I'm sick of having to hold the "pass"...

Hey guys, I'm at the track and the low oil pressure warning is coming on. Oil level is good any other common issues I should check? Thanks, Mike

Hi I just got myself a new RC390 year 2018. Since the last 2 week of using it I notice the heat issue where the temperature rise up to the barrier at H in traffic even though just short distance. But for smooth traffic like highway I don't have such problem. 2) When ride the bike in first...

I've had my 2017 RC390 for a few months now and am already having my first issue. I am seeing the "Low Oil Pressure" light during the bikes warm-up. It's a bit strange because the light will always come on while the bike is warming up, but once it gets to operating temperature, the light will...

Loved the bike till first service then it’s been plagued by problems. Couple days after the service it over heated to max bars and and left stranded on side of freeway. Never did it it again. Now it starts when it feels like it, but then dies at random stop lights. Have it plugged into a tender...

Hello Guys, Recently, I have a problem with the oil pressure. Last week, I rode my RC390 (2015) for 150 km, and went to the gas station to fill up the tank. After filling, I rode for 1~2 minutes, and the low oil pressure showed. (My bike's odo is 19000 km) I turned off, and re-started the...

I've gotten the LOW BATTERY warning several times recently; I trickled charged with Battery Tender Junior until green light indicated full charge; low batt warning gone, all good. However recently, I fully charged it after the warning came on, and now it's already back to low battery warning...

Bike ran great but had consistent problem shifting to fifth. Thought I had clutch adjusted on tight side with a few mm of play but you could feel something in lever as it finally engaged. Also noticed that pull is not as long with pazzo levers when they are set to anything but longest reach. I...

Finally getting to race the RC has given me a desire to get a slipper into it sooner than i planned. For my track a slipper will be more valuable for me than the brembo upgrade i was planning to do next. My biggest issues are a few downhill off camber corners where i am hard breaking into...

Made these videos last weekend and have since figured out the low oil pressure problem on my new motor thanks to help from Chad at Welcome to KTM Performance (I forgot to transfer the oil jets to the new clutch cover)... Before low oil pressure warning...

Theres this low battery warning that comes up if i leave the killswitch on for a while, say 5 mins, the bike starts fine and the battery voltages are fine when off and when engine running. Ive even Replaced to a new battery recently. What could be the issue?

I have been wondering about this for a couple of months. If you have ever held the passing light switch on when riding you know how much better it is than just the single high beam. I also noticed one of our vendors sells an LED upgrade and plug and play harness to have both lights on for high...

Hello, New to the forum so apologies if this has been discussed or is not relevant to the forum. I am 45 and love the playfulness of the rc390. I am in no way a racer but would love a track day for fun. Question here is, as much as I love this little bike I desire the build quality and...

Hello all, From India. With great difficulties i own an RC 390 and its been a year since i have bought it and till today i have the love on riding it and have done 30000kms only through the city traffic and one long ride of 2400kms ( Chennai to Pune ). now arises the problem of low oil pressure...

. So now that the PCV is installed. it was time to install the Dyno Jet Wideband Commander 2 ( WBC2 or WB2) p.n. 15-7023x........ so we could have more Control over the Fuel map on the bike. As many of you know the KTM 390 has a difficult ECU that doesn't allow closed loop to be altered...
