How many miles on the tires ? , worn tires can definitely cause a wobble , front or back .
Depending on how many miles on the bike , the rear swing arm might need attention ( bearings and bushings ) I would look there as well , you'll have to get the bike up off the ground , remove the belt and check for play in the swing arm .

Ok , I would focus on the rear , wheel alignment and bearing / bushings , change both sets . I had one bad bearing , dry as a bone . I ended up taking the swing arm off and had new bearings installed , at the same time , I replaced the rubber bushings and front engine mounts , mine are duel where yours is a single , could check that too .
Also , look at your top engine mount , if you can twist it with your fingers , you need a new one .
If your doing the work yourself , you could put thin layer of grease on the bearings to help them from drying out , I did on mine , my bike has 25k on it .

Yes! spokes were my issue om my 07 EGUC. I added 2 different types of stiffeners and upgraded bushings, still had wobble over 85mph. Pulled the rear tire off and figured might as well try changing the bearing on a 85k bike. Noticed that there were 4 spokes broken and half were loose. Got the entire wheel completely restrung. after that I can hit 100 and she is as steady as can be.
Funny enough, I just got new tires put on yesterday and have the wobble again....guessing the rear is out of alignment. Back to the shop today!

If you have spoke wheels, that is almost always the place to start. In the old days, my truing stand was used regularly to keep the spokes in spec.
Anytime you change a tire with a spoke wheel, it needs to be retrued. Especially as it gets older. The holes in the rim and hub wear out and become oversized or oval and no longer hold a good true for as long as before.
Also, Any bent spoke, no matter how small, will result in a screwed up true. Unless you are totally married to spoke wheels, I strongly suggest trashing them. They are terrible.
Most people don't understand how spoke wheels work. As odd as it sounds, the bike is actually hanging on only about four spokes on each wheel at any one time. That's right, the spokes don't hold the bike UP or disperse the weight evenly in a circle., The hubs, and all the weight of you and the bike, are hanging from the top of each wheel on about four spokes.
If the rim is even slightly bent. one of the spokes is out of true, bent, loose, not even with the opposing spoke, loose in the mounting holes or just plain old and stretched out........you will wobble.
Worn out bearings, either wheel, swingarm or fork, can usually be detected simply by jacking the bike up and shaking the parts in question. Play is almost always immediately noticeable. Not so with spokes.
