I recently bought an 06 vrsca and absolutely love the bike-especially riding the mountain roads. I have a problem getting to the mountains as the bike seems very unsteady on the highway. I can go 70, 80, even 90 on the backroads with no problem, but that's not the case on the highway. It feels like I have no control and the wind is blowing me all over the place. Any idea what's causing this? Is it common to all bikes?
