hey everyone, just got my RC 390 2 weeks ago!!!!!
Had 100's of track days on R6.
So I'm running A group 70% carrying decent momentum, going through very fast chicane (Portland International Raceway OR. Turn-7,8) and crash. (this chicane is simular to T1 at Auto Club Speedway, CA)
Wondering why...
The throttle tube is super easy to install. I knew it would only take a few minutes, so I set up my GoPro in Timelapse mode to capture the magic! :D
Maybe someone will find this useful?

Hey folks, looking for a Werkes exhaust if any of you have one floating around. Also looking for a G2 Quickturn Throttle.
PM' me and we'll have a chat.
Thanks!

I have been modifying and looking for more gains with the engine kit! I lightly blended the bore, cleaned up/radiused shaft and tapered throttle plate on first iteration.
Dyno data was collected same day back to back on stock throttle body to modified one. Found over a horse...

2 sets of aftermarket springs, will require PVC or similar spacer cut to length for preload. Good references in this thread. http://www.rc390-forum.com/forum/wheels-tires-and-suspension/301-front-springs.html?highlight=spring+spacer
One set has a spring of .95kg the other is 1.05kg, giving...
Favorite local dealer (Taylor Motorsports) had been bugging Motion Pro for a while now and finally got the Motion Pro revolver kits in.
If you're thinking of buying a quick turn throttle, this is by far the best, I've tested everything available and this is second to none.
Does replace...
Rant mode ON.
Okay, courtesy of being unable to drag the throttle side grip across the retaining nubs (to re-use it on the G2 throttle tube I have ready to install), I made the decision to pull the clutch side grip and replace it as well. Normally, I can just inject some water under the grip...

I discovered the rc390 has a throttle tube that is made of plastic and it has ridges at each end that keep the grip from moving. The throttle tube is also shorter than almost all of the replacement grip sets I tried. I have never seen a throttle like this and was wondering if there is an...
Would a snapped throttle cable be covered under warranty? Is it worth the effort taking it to the dealership? The parts less than 30 bucks, how difficult of a job is this? I'm a master auto tech but something about working on my own bike kinda irks me considering how hairy sh*t could get if i...
Going to document all parts used fitment and etc here for archive usage.

If you've never had a quick shifter, you are missing out some enjoyment.
Being able to just fly through the upshifts, while never letting off the throttle, or pulling in the clutch is soooooo nice.
Obviously for any racer challenging for wins.. this is a must.
But, even all our street...

Hi all,
I have a 2015 RC 390 Cup bike. The KTM experience has been less than ideal so far. During the typical warmup before track use (Track bike only as CUP bikes are not street legal) when the bike reaches 4 bars (temperature) on the display the bike just shuts off. When I say shuts off it...
Basically long story short, while riding yesterday about halfway through my ride I went to overtake a car and pulled back the throttle and nothing happened. After fiddling around I realized I couldn't exceed about 6500 RPM in any gear except 1st. I would be cruising totally fine and go to open...
My RC has the Akra pipe and map but still has that annoying surge when I roll the throttle on at the apex of a corner. It really upsets the bike.
I dont know if remapping can fix it (maybe by adding fuel at the lower rpms?) but I was thinking about simply increasing the engine idle speed in...
