I push my Loopframes hard & never have I had a problem with instability. While racing the V-700 last year, a guy faded out of a turn & bumped into me at around 70 mph, the bike thankfully stayed rock steady (I did have to clean my shorts later). The bike routinely gets run into the triple digits without problems. Having said that it does have a steering damper, new rear shocks & I pay close attention to the head & swing arm bearings.
If you have wobbles check swing arm bearings head bearings rear shocks front springs
