I don't take my hands off the bars so wobble isn't a concern. The biggest culprit is usually the front tire. If the front tire is worn, maybe time to replace. Do you frequently take your hands off the bars? I usually use my feet to steer and my hands to mix drinks or to shave. You opened a can of worms with this one. You can do a search. Pretty soon you will be replacing the steering head bearing, getting a new/different brand of tire, changing tire pressures, changing to triple chromed Superbrace, Dynabeads, different rear tire!, etc. The main reason the Wing has wobble is due to fork and chassis geometry, like a caster wheel on a shopping cart. This geometry makes the Wing a great handling bike in my book, I.E. light steering effort at speed. Another potential way to fix this, besides not letting go of the bars or spending money, is to raise the rear of the bike to a higher setting, which changes the geometry of the bike. Good luck. P.S. I want to know why I drive off the road everytime I close my eyes.
