    2nd Radiator (real fix for your cooling problems for $750.00)

    Hey so I don't normally post and I know this could/should go in the technical forum, but I think this one is important. Many of you have notice by now that the RC390 is not, actually, Ready-To-Race. In fact it's not even ready for particularly hot weather. There are three problems that I had...

    2017 RC390 - Temp Gauge

    Hi, Everyone. I recently purchased a used 2017 KTM RC 390 at an amazing price with only 500+- miles. With that said, I took it out in its first ride today. Five miles throughout the neighborhood, not exceeding over 25 mph in speed much at all during that time. For a couple city blocks I did...

    2018 SPAL radiator fan swap

    Got my bike apart today to do a handful of mods including swapping to the SPAL fan. A couple of observations and a question... My 2018 doesn’t have the fan shroud I’ve seen on the earlier bikes, when did they change, 2017? Did they also upgrade the fan making the SPAL swap not necessary? Seems...

    Manual fan switch diagram

    Does anyone have a diagram or tutorial how to install a manual fan switch? From what I understand you just run it off the battery >fuse> switch> fan power. It is for a track bike and currently my fan is kicking on pretty much right as I park the bike after a session. Would like to run it when...

    Manual fan switch

    I'm curious, has anyone installed a manual fan switch on their rc390? I'm not worried about the bike why i'm riding it, its when you cut power to the bike, the fan doesn't stay on. If I turn power back on after riding it then parking maybe a minute later, i'll notice it sometimes will be...

    My first RC390 :) Ongoing review..

    **Side note I am probably like most of you guys and been riding for 30+ years with far too many bikes come and gone. But this is my smallest bike ever owned and I'm looking forward to it more so than many others that have passed through the shed :) Took my little beast up my local hills to...

    G'Day Mate from Oz

    Live down under in Melbourne. Got my RC back in August. Had a little YZF-R15 150cc which wouldn't do 100km/h up a hill or in to a wind. 100 or 110km/h being the legal limit over here. Was saving for something like a Street triple as the next post-learner's but saw a dealer throwing out their...

    Cooling fan

    Just a random thought. Fan is Ecu controlled, so ktm knowing about all the head gasket issues should do an update on the PCM to lower the temp at which the fan comes on. Seems like a super simple fix. Drop the fan temp on time to 90 deg or something. Maybe that would aid in the longevity of...

    Hot Hot Heat - Or How to Cool Your RC390.

    So it finally happened to me, the OEM fan has failed on my bike and it sounded like a baby seal dying during the process. Now that my bike is over heating I need to replace the fan (that I could do under warrantee) with something. Everyone has said that the SPAL 5.2 Inch Puller Fan is the way to...
