Probably the only video review/build on a KTM out of the possible hundreds I’ve watched over time. I’ve wanted this bike in almost any fashion for a long time. But no one ever edited a video of an upgrade video like this one, that I’ve seen yet. Awesome work, brother. Hats off to you. *drives to the local shop*
That's awesome have fun, I'd recommend learning to drive for a while in a car, and then using that knowledge on a bike, rather than learning the road on a bike, but yolo!
On my 2015 KTMRC 390 Racing Bike, my Favourite thing was to get rid of the Lead Acid Battery and fit a Lithium Ion Battery Instead. I don't want to tune it up. It's Fast enough to go screaming down the Road with the front wheel a foot above the ground with me leaning over the front of the Bike ! It's Eight yrs old now and is Running Fine !
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 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 just installed the coober ECU, K&N filter, and coober airbox lid. Expensive but it definitely enhances the ride dynamics and smooths things out. A little extra power too and adds a nice throaty exhaust note.
@MybeautifulandamazingPrincess Thumpers are fun AF. Take it from a long time RC51 owner. My Duke390 is just fun and easy to lay in to corners. Super all around town bike.
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...
I've used 300V oil since I've owned my 2016 390.... recently changed my clutch out and inspected the inside of the head @ 20,000 miles and still looking like a brand new engine on the inside.
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.
I really liked the tire swap front and back. They add the aggresive look of the bike instantly Even the exhaust sounds great...rest I would leave on. Great jobbuddy, you have more skills to do the rest...
YOU may have just SOLD a New KTM for KTM Brother, After watching THIS Video i;m really thinking of getting A 390 DUKE [Probs NEW 24 Model] I love the way this Little Bike looks [After coming off Bigger bikes S-Sports] Because of Back Injury. Making the bike your own IS Part of owning Bikes and this Video is Well made Congrats/Best Wishes/Safe-Riding Wales [UK].
❤ most of ur upgrades. Air cleaner , exhaust & ecu. ❤ the original tank color scheme with the 390 & Duke logos. Why KTM would delete this from there current 2021 models is beyond me.
I have one of these, great little bike. I am in my 50's and don't need anything bigger and faster. What I have learned over the years is upgrading stuff, I have done both on cars and bikes, is a waste of money. If you want more, put the money into a new bike and change the 390 up to the 790.
@@ClintEwingFreestyle Hey Clint, thanks, what you did with yours is very interesting and the bike looks great. I am not pissing on what you did with yours in any way, I'm probably getting less inclined to spend money in my old age! By the way, I know another Clint Ewing in Ireland!
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.
Stiffer spring: maxing out the clicks on the stock spring for resistance was insufficient for you? I've got my 125 at 10 clicks and I weigh 240lbs! I'm with you, I prefer the stiffer suspension as well. What final gear ratio are you using? I thought that would make your top 10.
How about sprockets? I'm thinking of changing mine on my cb400, I only ever do city rides and max only hit 110kmh on highway (legal limit and I can't risk a single point)
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.
I hear some other videos and posts describing issues with the brakes, the lights fogging up, the leaky head gaskets on some of the earlier production models. I'm curious if KTM has done anything to address these issues, or do these issues still plague this bike?
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.
Could you recommend or suggest the underseat twin exhaust for duke 390? It's better if you made a video about termingnoni,twin exhaust like in panigale v4.
Hey what’s up. Did you have to mod the small werkes exhaust to fit the bike that is already done. I have a 2020 and wanted to go with that little werkes exhaust but it says it won’t fit.
the black exhaust box is called the pre-silencer not the cat the cat is the next pipe up its confusing but I found it out the hard way by purchasing the Wong pipe hahah
It seems like you have lot of experience with the maintenance of ktm bikes. If i may ask you can you make a detailed video about huge weight differences of duke 200 (old version) of 2011 and the current model
How is the handling on the larger tires? Is it getting pinched. One of the great things about the duke is the light flickability and steering. Is that effected? Thanks
Its just my opinion but I love the option of better tires (grp300) (q3) when you go up in size. I dont notice less flickability. Love the extra traction.
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.
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.
Great build.I am curious about the handlebar and TFT display and what kind of custom bracket did you make. I can't get the idea of this stupid 26.5 mm handlebar diameter and the restriction of the original stem.
Some bad advise here - If you upgrade the Air Filter you MUST replace the ECU with an after market one. These bikes run lean and adding more air without increasing fuel flow is bad news.
@@alvin5603 What is the title of the video? He adds the ECU after. If you listen to his so called top 10, he makes it sound like you can do any of these things. Which is 100% wrong. He NEVER STATED, that you MUST change the ECU if you change the air filter. Right. Isn't it?
I dont see any kind of link to the seats you put on here? Why would no one be asking about that... comfort is probably one of the most obvious and important upgrades we need here!???
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?
@ClintEwingFreestyle okay second question if I was to add the airbox lid and just the mini cat delete or "de cat" keeping the stock headers & stock exhaust will it throw a code? Or have throttle lag? To the point I will need to upgrade the ecu
Hi Clint, Thanks for the informative video. As you advised before I have ordered the 1fngr duke 390 air filter box lid and it's about to come. It would be really helpful if you could update me with the purchase links of the protaper handlebar and the risers. Thanks in advance. Regards, Subhojit
Hey great video. Any chance you could link these products in your description? Also how were you able to remount your display using the new bar mounts? I'd like to go with a more low profile wider bar but need to change mounts in order to do that. Thx 👍
Can anyone recommend their 2023 year choice between the CB300R, Yamaha MT-03 or Duke 390? I’m 5’11” tall, 175-pound weight, with a 34” inseam pants size. Thanks!
