At this point in time buying the highly regarded Akrapovic open or race system is not an option in the US, it was removed from the KTM North America webstore sometime recent. So if you want the highest performance exhaust now its the Tyga WSS 300 or buy the Akrapovic with the cat 90805999100 and...

We now carry a full line of Rapidbike products... Why? Full auto tune capabilities out of the box, with CLOSED LOOP fuel capabilities. That right there should sell you and if it doesn't, know that the 390 EVO Exclusive retails at $395. That is $25 cheaper outright then a base model PCV, but if...

I have some parts that I took off my bike for race conversion that I think people could find good use for on a street bike. Would like to sell the parts local, but obviously that isn't always possible. Prices below would be for local pickup. If you are not in the SoCal area, I would likely add...

Many of the aftermarket exhausts for four stroke MX bikes had a add on cylinder reasonably close to the engine that appears to be a boost bottle (like the old two strokes of the early 198s) that I am a familiar with. I was wondering why none of the aftermarket exhausts for the RC390 do not have...

Hello I modify my RC for track but want to keep it still road legal. I'm planning to use TYGA front fairing, then I have a question : if I simply add holes, is it possible to mount the stock mirrors? (I plan to add lamps to the mirror in order to have high/low beam anyway, and remove them for...

From SuperbikePlanet Hard for me to get too worked up about this. KTM took so long to get the RC8 to market that the "superbike V-Twin" wave had long since passed. Add to that high prices, limited availability and even more limited support, and it's no wonder I'd forgotten they were racing at...

First of 2...just finished last night for a shakedown at the track on Sunday. I still have Rearsets, sprocket, traction pads, seat, etc to add before then but I am really happy with the look the Tyga-performance glass gives it and the super clean colour.

Hi Chaps I have a few questions on the above, I have read through various threads but just need a bit of clarification before I buy. Here goes 1. If I buy a PCV from say a forum sponsor it will come with a map kindly supplied by them, otherwise it will come with Dynojets RC map? 2. The PCV...

Hi Guys, Need to add some coolant to my 390. Do you guys have a suggestion on the best brand to use?

So we all know this bike runs hot. Has anyone tried water wetter as a coolant yet to see if it makes a difference? I have used it in my other bikes and noticed some difference. Also, i just got my bike, only rode a few times so far but just noticed today that my coolant level is just above the...

Can we add a section for classifieds? Bikes, Parts, etc.

Reposting since my previous post disappeared (?)... KTM thinking about adding a Slipper Clutch to the RC390... KTM to introduce slipper clutch on RC200 & RC390 | Shifting-Gears This is a very good idea as that high compression single cylinder is going to have a lot of engine braking... A...
