    Clutch wear, replacement, and gasket

    23,000mi on 2016 rc390. Haven't ridden it much this year because riding an sv650 more frequently. Noticed the past several months that the clutch feels light and seems to have a narrower friction zone than I remembered it having in previous years. Wondering if clutch plates are worn since I tend...

    Head Gasket Blown

    Sooo... It happened. There are bubbles coming up in the rad and the bike gets hot in a hurry. While I have the heart open, what else should I do? Should I change the rings and chain? The list so far is pretty short, just change the gasket, check valve clearance. Any advice is appreciated!

    How many head gaskets let go?

    I think you guys are the authority on this topic but I’ve been out of the 390 game awhile. I got out in time but had doubts my 15 RC would go the typical 25,000 I like to use a new bike despite a sweet Chad tune and measures to keep it cool, in street sport riding. Anyway, my son called me...

    How to avoid head gasket problems (new rider needing help)

    So from what I understand (which mind you, is not much) a seemingly common problem is a blown head gasket and it seems like it's caused by overheating. I bought a new 2017 rc390 a few days ago (my first bike and I'm loving it!) and I have noticed that the fan has to kick in pretty quick...

    blown head gasket

    Blew the head gasket on our new 2017 rc390 yesterday. I was aware of the problems and made a lot of mods (spal fan, rad cap, water wetter and pcv with richer map) to hopefully avoid it. Blew any way at just 3000 miles! I've read that KTM has an updated cylinder/head that resolves the issue...

    High mile RC's

    I'm a bit worried of what the future holds in relation to my RC. I am loosing faith after reading about, head gasket, clutch and a few other common place issues happening. Are there many "high" mileage owners out there who have had zero issues??

    RACERS! Reliability Report.

    Dear fellow racers, I am curious about how the reliability has been with your track RC390? If you have had issues what are they? To start this off I have had a blown head gasket, valve retainers fail and take out the exhaust cam, and a piston crack in half. I am looking to see if there are...
