Sorry that's already sold.

@KodakMoment @othebe Ok, so after I finally tore down the engine I can now tell you what caused that. At first I thought it was a broken impeller fan, but no. Big end bearing failure. That caused the classic thrown rod. I've decided to part ways with my RC390, so if you are interested in...

I put this up on eBay, but I know one of you hasn't done this modification and, well, you are going to regret not doing it. The fans explode and the radiator cap does not stay on. $100.00 + shipping via PayPal for everything with shipping and I've installed the puller fan for you. All you...

I'm afraid I'm going to have to part ways with my much loved and insanely built 2015 RC390. It had every light and/or fast race part you can buy for an RC installed on it. It has never been tipped over or crashed. The average part has seen less than 10 days at the track. It's has two sets...

Way late to send this, but I have all the parts you need and you can have them for cheap. I have a 2015 top end put together by Spears racing. It has all the fancy shims and such from here: http://www.ktmperformance.com/ktm-390-performance-valve-spring-kit.html. Shoot me an e-mail if you want...

I have a full setup for sale. Driven. I'll throw in the Woodcraft switch eliminator and the motion pro ignition switch. $200.00 + shipping for everything. [email protected].

So after 3 track days in 100F heat I can say two things: The bike ran much cooler BUT I think the post above may have been sadly prophetic... https://photos.app.goo.gl/q5KcKKQqmppgZa3o8

See my post about the 2nd radiator. Game changing difference in how hot the motor runs. The R3 has less issues, but they still die. I think the only way to have a solid small motor race bike is to regularly replace the motor. You got 3 seasons. I got 1.5. I've been told: 1. Change oil...

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...

I'm about to post about the extended radiator, but the answer to your question is that you must install this part or your bike will not last very long... https://www.hsbkracing.com/parts-and-apparel/ktm/rc-390-390-duke/radiator/febur-ktm-rc-390-secondary-auxiliary-radiator-2015-to-2018/

I'm sure this has been covered, but I'm having some clearance issues on my 390. I put BST wheels on and they are great. Good for 2 seconds. The only problem is now I'm starting to drag the right side T-Rex case cover and the back edge of the belly pan. I'm going to swap out the case cover...

Yea I bought it. :)
