What condition is your front tire? Spun balanced or static?
If the tire isn't the culprit then check steering stem bearings.

Some bikes show sensitivity to certain tires even when the tires are new. Add that to steep, quick-steering front end geometry and you have a prescription for wiggle.

Is it possible you lost some wheel weights? Your tire could also be defective.

Maybe theres a flat spot on the tire ?
Check to see if the rotors are warped?

Mine used to do the same thing... i replaced the front wheel bearings, and it took care of the problem.

My vote...front tire.Sometimes would 'wiggle' at between 40-50 mph steady speed,or deceleration.Not a shake...a wiggle...very tiny.Tires always cured it.
