After the official Vit/Svart message board seemed to get switched off, I found myself homeless on the Internet. A quick search found this place, which seems to be a lot more active.

By way of introduction, here is my 2020 with a few (hopefully tasteful) mods.

This appears to be the full KTM 690 exhaust. The OEM exhaust hanger doesn't fit correctly - how did you solve that issue? Is yours custom? Thanks.

Who's system did you use for the single intake filter? Was it Bad Winners or a custom setup?

No system required, a K&N RE-0930 filter will clamp straight onto the standard intake rubber. The rest of the airbox plumbing was taken care of with a couple of mini DNA filters. Surprisingly easy mod to do.

Yeah, the Akrapovic system on the Duke is spaced out high and wide when offered up to the 701, I cut about 30mm out of the link pipe between the two exhaust cans and rewelded at an angle to meet the Svart fittings.

You must have done some jetting mods as well - do you have a PCV? Dyno tune or seat of pants? Big changes to the AFR? Did you notice any difference besides sound?

You are the second person to do that . . . or are the same person. Bike looks different though?

PCV with an open airbox map, on top of a fuel dongle. No gaps in the power or flat spots but will probably benefit from some dyno time. It certainly feels like it has a huge amount of extra thrust in the midrange but the increased induction noise almost certainly has a misleading effect on my seat of the pants dyno.

I have seen a couple of others, Vits I think, who have taken different approaches to the same mod.

The "open airbox map" came from whom? I haven't heard of this yet. Is it from Rottweiler? Is this something you can share?

From what I've seen of the aftermarket filter like yours, they have added a length of pipe between the engine and the filter, elongating the intake tract. I think this helps with low-end, mid-range.

I also have a Svart and the Akro, but went a different route: I designed and 3d printed a bracket, keeping the pipe in the same position. It's lovely but my boot heel occasionally contacts the pipe, so I had to install some adjustable footpegs and find a sweet spot for comfort that doesn't force my boot to contact and melt.

Thanks for all the info. Cheers.

The map is for the airbox lid removed and a decat exhaust, available on Dynojet website. It runs pretty well but will need tuning on a dyno to optimise.
 
I am not sure if I am a fan of the huge hole in the center of the bike.

As I havent had the airbox out myself, maybe you can answer this for me - Isnt it possible to fit a cone filter inside the original airbox, or maybe one of those ramair foam ones?

It would be totally possible, just involve cutting the airbox about a bit. The look isn't for everyone, it probably works better with the black subframe versions.
 
I am not judging looking to give advice on what others should or shouldnt like looking at.

I think its cool when people do stuff they like!

For the airbox, the snorkel goes inside, kinda wondering how is it attached - and if is it possible to just replace the snorkel with a cone filter without modding the box?


Edit: And for clarification - the open subframe makes me think of those dirt bike grab holes for doing like superman st7nts.

You might be able to put a smaller cone filter inside the box, but I suspect there would be less benefit to it than just removing the airbox lid and keeping the stock filter. I ran the airbox without the lid for a while and it probably isn't that much different performance wise than ditching the airbox completely.
 
It's open on one side with a big filter. Like the concept bike. He cut open the stock airbox and modified it . 3d printed some adaptors and whatnot. And got a smaller antigravity battery. He made a few post about it. But the forum is down now
