If there is no traffic in front or passing me, mine is stable at high speed, but if the air I'm cutting through has been disturbed by traffic, it will occasionally give me a couple of ocillations, but not a continious wobble. When it does ocillate from turbulent air, I pull straight back on the bars, tuck my knees into the tank clench everything and it smoothes out. The wobble I get is not like the wind blown fun I used to endure on the Suzuki 250 Boulevard. In clear, un-cut, air your chrome cousin in Canada runs up to top speed well.
