[@ivanscicluna2988]

I have owned a KTM RC390 2017 model and did almost all of these mods, and honestly save yourself the money. After spending over 1,500 the only thing which actually made the bike faster was the Rev limiter increase with the powertronic. If you really want some more speed get yourself a larger front sprocket and smaller rear sprocket as the bike already revs extremely fast. Don't mess with tyre sizes and shock springs unless you plan on taking the bike on track

[@c.a.marsupial.1282]

What's wrong with going for a 160 rear if you could help me out there as I've been thinking of doing it. Thanks.

[@ivanscicluna2988]

@@c.a.marsupial.1282 Ideally keep the tire factory size, a larger tire means a larger contact patch which will make your bike more stable on straight roads and help with wheel spin ( which isn't a real issue on a 390 ) but you are sacrificing mobility as the bike will be harder to lean or turn. If you want to do it just make sure it's for the correct reasons :P and it suits your riding style

I've used the power tronic system with the quick shifter for a good while now on my 2014 model. i also use a 02 eliminator from dyno jet for a open loop. it really helps with the lower grunt for the bike, great combo with aftermarket exhaust and air box mod with k&n filter. Glad to see so much love for the duke 390...

You can also lower your front forks in your triple clamp by 20mm to 25mm. It will give you better front end feel and cornering but not good for wheelie.

Ryan F9 reckons the RC390 with the same engine runs a little lean, does the ECU you put in run it a tad richer, especially with the higher airflow?

[@majormassenspektrometer]

Every manufacturer tends to make their bike lean to get to the Euro 4 and Euro 5 emission standard.

10W40 is too thin for the 390, because the single cylinder runs very hot. 15W50 is whats recommended in the users manual.

Wider tires just add a bit more weight and slows down the dropping in to the corners. Wide tires are needed for traction but thus lil thing doesn't need that with its slippet clutch and fairly light weight.

If you don’t have any loudness issues in your country you can replace that on the exhaust. It is not the cat! It’s the premuffler. The cat is round and seats before the premuffler.

If I was to just get the coober air box lid only will I still need to replace program or get a different ecu? Will it throw a code or have throttle lag with just the top lid for the air box?

Dont NEED to but helps balance out the increase in air intake.

[@satthu0264]

Hi Clint, I'd like to ask about the effect of the air box lid. Thank you.

[@KoryKinnett]

I can probably respond to some extent on this. I purchased one after reviewing this video, I've noticed that the noise produced from the bike has become much more prominent. More so than the noticeable difference made by my Leo Vince slip-on over the stock exhaust on my 2018 390 duke. I've noticed that I get more glances and stares and it's quite noticeable by the rider as well. Feeling and hearing more noise coming from between your legs. Additionally, I've had this about a week, of which today was the last day of rain. The box and lid/foam seems to do really well even when put into extremely humid and wet environments. As far as performance goes, I've not done any other modifications (including no ECU upgrade (still running stock)) and I've seen a slight performance gain, especially in the 3k-5k rpm range as well as up in the 9.5k-10.5k (redline) rpm.

[@KoryKinnett]

Too early to tell on gas mileage, but I want to say that it might be slightly less.

[@satthu0264]

Kory Kinnett which Leovince slip-on are you using, bro? I also use the Leovince GP One for my Duke. At low rpm (3k-7k), it accelerates noticeable faster the original muffer. But at high rpm (7k up), it choke for a moment then speeds up. Now I'm considering to upgrade its air filter to see if it could fix the problem.

That's not the Cat you are pointing to. It's the main canister. Cat is just above it on the other side of bike which your part does delete as well. I would remove the main canister as it weighs a tonne. Mufflers, without header and tuned mid section do little to nothing for power on the 390s, just noise. Best mod is ecu as they run way to lean from stock which makes them jerky down low and run hot. Should be way smoother now.
