Considering that everything else is good in the front of your bike wheel balance good Tire Etc a lot of people claim that going to the All Balls bearing kit eliminate the wobble. I recently just purchased the helibars for my bike and they should be arriving soon. and I'm undecided whether I want to change the bearing in mine while I have the handlebars off as I have the wobble too. And I just had new tires put on mine and the dealer check my head bearing and they say they retorqued it. And I have about 10,000 miles on my bike. It is snowing here now so I still have time to think about it.
Need more info. Tire pressure front and rear. Mileage on tires and mileage on bike. Be aware that a problem at the handle bars could be manifested from the rear tire. Bad tire to loose lug nuts.i
To put this as nice as I can, if I had a problem I would not be looking for a patch.
You will travel better fixing it.
Step one, identify, then
Rectify.
Then make it supposedly better with the snake oil.
Some are, some are not.
