Unlock Your Bike's Power: Front Suspension Upgrade
Вставка
- Опубліковано 27 лип 2023
- Upgrading your suspension is a simple and affordable way to make your bike faster. By upgrading your suspension, you'll improve your handling and speed, making your bike more responsive and fun to ride. If you're ready to boost your bike's performance, then this upgrade is for you!
Stock suspension works well for road riding but as your skills improve or if you ride on the track then you can ride faster and more safely with an improved suspension system. One of the easiest ways to upgrade is to follow the same path as KTM and fit the White Power Apex suspension, and in this video I show how easy it is to replace stock front suspension with Apex - a better system with the added benefit of being able to adjust rebound and compression so that you can dial in the bike to suit you and your riding style.
KTM part numbers for the fork legs (order from your dealer) are:
94801001000
94801002000
But note it would be cheaper to buy the Apex Pro inserts from White Power/ WP dealers.
Torque: Wheel spindle 25Nm, Fork stub 15 Nm, Brake calliper 30Nm, lower triple clamp 12Nm, upper triple clamp 15Nm

Now, I’m just a normal guy who likes working on bikes; I’m not a qualified mechanic but I’ve spent a lot of time working on bikes and most of the servicing you see is directly from the manufacturer workshop manuals. I like to show you interesting things you can do and that I’ve done with my bikes, but I can’t promise you that anything I show you will work on your bike as not everything is always exactly the same. Be careful not to harm yourself, anyone else or your bike and always be aware that if you have a warranty then changing or working on your bike can invalidate it - they do love an excuse not to have to pay out. If you have any doubt then talk to a qualified mechanic or engineer and make up your own mind. - Авто та транспорт
Somehow managed to miss this. Nicely done. Glad she’s performing well for you.
Great to hear from you again. Hope you and the family are keeping well.
Good sharing 🔥🔥🔥
Thank you! Cheers!
Nice. I'm really looking forward to my upcoming andreani/ohlins upgrade.
Tu verras c'est un regale ca transfigure la moto que ce soit en courbe en freinage. Bref que du bon
If anyone's wondering about the new 2024 rear suspension of adv 390 and new Duke 390 it fits perfectly on 2017+ 390 models too i don't know about the 2016 last model. But on old models the soft and hard settings screw is a bit hidden can't access it correctly but everything else is a awesome upgrade.
I covered the factory modification you need to do so you can easily access the setting screw on my recent video on the rear suspension upgrade.
I did the same exact upgrade earlier this yr. These forks are actually a couple mm longer than the stock forks so if you gave it lined uo with the lines on top of the forks, you end up raising the front end. I have my front end lowered quite a bit to get it to turn in the way i want it. You may not notice if all you're doing is street riding
Interesting thanks, I hadn't measured it that closely, but yes always a factor in what works best for you. I will experiment a little and see how it goes. Thanks!
But isn't it the same size 43mm ?
Hello, it’s not a question about suspensions but i hope you’ll be able to answer me. I’ve got a duke 125 2018 with akrapovic slip on and i was looking to change the baffle with a louder one. I found one which is 54,5 mm, do you think it will fit? Thanks
Great video! Where did you get the front brake caliper vent/cowl?
Thanks. Bagoros Performance
Great video, David. Was wondering if you knew anything about raising the forks in the triple clamps to get more front end feel on the 390 Duke? Can’t find any one who’s done this on the forums…
Thanks. The only people I've seen doing it are short people trying to lower the seat height. But I have heard of people doing it for track days - usual caveats apply - make small adjustments only. You might want to consider this upgrade if this is your rationale. Stock forks are good enough for road riding but there is a reason all the KTM and Husky range have been upgraded.
Nice work and much appreciated. I saw the 2024 was coming out with adjustable and wondered if i could upgrade my 2023. Any feedback after a month or riding? My reason for the upgrade is I would like to soften up the ride for the long highway rides (no shortage of potholes here), then adjust back for the twistiest. Not sure of the validity of my thoughts.
Thanks. Very happy with them, much better ride and sounds like they would suit you much better. No shortage of potholes here either! Typically I'm running at the sport end of the adjustment because twisties is largely the reason I have this bike.
@@MotoMirius Thanks for the feedback. Good intel and thanks again for the channel and your content.
For rebound bro... What is the best settings for race.. I have rc390 v2
It depends on your weight and what the course is. I suggest that you work with the settings and see how they change your ride. Much better if you can play on a track so you can see the results of changing so that you can find what works for you - just do a few laps to settle in then move it a couple of clicks and go from there.
@@MotoMirius Thank you brother for the reply.... I will try this recommendations from you
Hi .. I went to cartridge adreani adjustable with oil
olhins and it’s day and night ... The apex is next to and drop below and in addition I gained 1.5 kilos less on the scale
You should be comparing Apex Pro to Ohlins, not Apex - you get what you pay for with suspension and I'd be very disappointed if the Apex was as good as the Ohlins. I think Andreani is closer to the Apex.
Hi David , @Motomirius , where did you bought the sump guard / under belly protection plate?
Thanks..

Hi! can you possibly do an overview of the current road crash protection in total like what you did a few years ago for your stunt bike setup? been watching your vidd since my Duke 200, might upgrade to theb390 soon. Its been years. cheers.
To be honest my setup hasn't really changed. I still use the rear cage because it provides protection to the slip on. But I will see if I can do an update. Thanks
also, how has e rok bagaros frame sliders held on? I remembered the installation was only torqued to spec with no loctite. is it still on nice n tight? I really appreciate in all your videos when you mention the torque specs😂. has helped me loads!
@@Rose__L Thanks. Very few of the bolts that hold your bike together have loctite so I wouldn't lose any sleep over that. They are still firmly mounted, can't say I've crash tested them (yet)!
Hi. Love your videos.
I bought Duke 390 2023 15 days ago.
I'm thinking of removing exhaust/muffler on the side(slip on?)
Will it affect engine in long run?
Issues with air fuel mixture?
A lot of people say it wont do any damage, but a lot are also saying about back pressure and how it ruins engine.
Please help.
It's not a simple yes or no - which is why you will hear conflicting opinions - but also there are people who don't know anything claiming that any changes will damage your engine. If you've made no other changes - air filters etc then you should be fine. But to safe you should consider investing in a piggyback, even if it just the FuelX Lite, because if you make this change it is likely you will be tempted to do more.
@@MotoMirius Thank you so much. I had Duke 200 2016, sold it to get 390 2023 only because KTM butchered new 390 looks.
Power is more than enough for me. (for Indian roads). Coming from underbelly exhaust, 390 exhaust is just visually disturbing.
Apart from removing muffler I'm not going to do any mods.
will this work on the 390? any thoughts on the 390rc ecu on the duke?
390 Duke or RC - RC already runs this, this is fitting it to the Duke - pre 2017 Dukes should still work, I don't think they changed the fork dimensions.
Hi Mirius, i have an old Ktm Rc200 with a problem on the front brake, allready try a lot of things and non display a real change. There is anyway u can guide me or just review my steps to find the error? Right now im suspecting that could be related to the fork. Sry for the potato English
It would depend what the issue is. It can be difficult to diagnose over the internet because often the fact that you can't diagnose the issue is because you are overlooking something - and this will mean I can't either. However the front brake is mounted to the axle fixing part of the fork so unless the fork bottom is damaged, I'm not sure how the fork will be involved since the axle and wheel do not move with the fork?
Hi sir Does the Apex suspension fit 2016 RC 390-(Gen 1). ??
Is it the same with rear monoshock??
I dont have an RC so it's hard to check, but this is the suspension fitted to the current RC, so it is very likely the same.
@@MotoMirius thankyou sir.
Hello, can this be done to the 2015 RC 390 ?
Probably. RC is different. But the RC changed to this long before the Duke was upgraded and I don't think the RC changed so much. But I don't run an RC so I don't track the changes so closely.
Hi, can you make a video on how to adjust valves for us regular viewers. I have a 2019 KTM 390 Duke. I am in Germany. I took it to the KTM dealer for the 15,000KM service , rode it for a week or so, but I can hear a noise, and thinking they did not adjust the valves correctly or did not even do it at all. It’s under warranty. But I now don’t trust the shop I took it too. That’s also where the bike was bought it from previous owner.
I'm not ignoring you, I'm trying to rework my work space because it's now so full I can't film in there - it will be a while before I get to this.
@@MotoMirius all good. I’m unsure of how to send a picture to you about my work space. lol. We all need just a little more space.
Hi, where can I order this WP suspension. I have a 2019 KTM 390 Duke and would like to upgrade. Thank you.
I'm not aware of anywhere you can buy it new - but you can find it from someone breaking an RC or a Husqvarna.
Sorry, a moments thought - you can buy them from your KTM (or Husky) dealer. I have added the part numbers to the video description. But it would be cheaper to go straight for the Apex Pro inserts.
How much did you pay for the front fork?
I paid £350 for a complete forks and yokes.
@@MotoMirius that thats the whole assembly on both sides?
@@reghz Yes, the complete unit including front axle.
@@MotoMirius its actually not expensive than I thought. Thanks!
@@MotoMirius I have one more question for you man if you don't mind. Planning to install a slip on and resonator delete on my rc390. Do you think I can get away without an auto tuner like fuel x? Thanks
Probably should have put fresh oil in them when it was easy to do.
It’s always easy to do. But that would be another video.
