I had an 07 husky 610 dual sport, wasn't much on the trail but I had a set of motard tires built and it was a hoot on the street. basically gave them away with the bike when i sold it to a buddy. but I couldn't keep up with all the crud in the barn, he is getting some fun out of it now, rides it 99% with the 'tard wheels on

Be VERY careful of putting SuperMotard wheels on your GasGas.
You will have so much fun with them you will never take them off.
It will ruin a perfectly good dirt bike......Or you will have to get another
dirt bike......At least that what I did.
Motard is so addictive, I now have (5) of them....
Here are three of them
A Derbi and a GasGas 50SM
The KDX240SM

I have a set of 17" ktm motard wheels. will they fit on a 2006 EC300. Has anybody try this. or is it to much work. thanks
Back to the original topic.
I did something similar with my Bimota BB1 Supermono some years back, when I adapted a set of PVM magnesium wheels from a Ducati TT2 to my BB1. The Ducati has a left-hand chain, while the BB1 has a Rotax engine with right-hand chain. Quite a few hours in the workshop with miller and lathe...
I also plan to adapt my OEM GG wheel to the KYB fork that I plan to mount on my 06 EC200.
Making the front wheel fit should be pretty straight forward. If you have access to a lathe, making a set of new bushings for the Gasgas axle is pretty simple. I presume the KTM axle is at least as big (in diameter) as the Gasgas one. Of course you must make/buy an adapter for the front calliper to fit the bigger brake disk. These can be bought as Gasgas OEM parts, both for moving the OEM Nissin calliper out, or for using a standard "40mm Brembo" calliper. These "40mm" callipers can be found everywhere, both as Brembo calliper or more exotic ones like ISR, Beringer, PVM, AP or others.
You may have to move the wheel slightly sideways to line up the brake disk and calliper. A mm or two in either direction should be no big issue, but if it's more than that, I would consider making a bespoke calliper bracket to align things properly.
The rear, OTOH, might be a more challenging task. The chain line has to be correct. The brake calliper must be aligned with the disk. The first thing to check is the distance between the sprocket and brake disk. If this distance is the same on the GG and KTM wheels, you have won the lottery. If the KTM distance is narrower, the hub may need some adapter rings to space the sprocket or disk out from the hub. If the KTM is wider between disk and sprocket, you may consider a new rear calliper bracket, or turning down the KTM hub.
You must also check that the rear disk diameter is the same. If not, you can solve it by moving the calliper using a new calliper bracket. The same bracket can of course be used to align it sideways if needed.
When the chain line is correct, you must also ensure that the wheel sits on the bike's centre line, and that the wheels are correctly aligned. If it doesn't, the sprocket may have to be moved sideways. This can me done by making a offset sprocket front or rear.
These tasks may or may not be easy to do, depending of the differences between the wheels.
As you have both GG and KTM wheels at hand, the first thing to do would be to take all the necessary measurements. What you then find, will tell you how hard it would be to do the conversion.
