Has anyone had a bike that they didn't feel confident riding on or just had problems riding well. The reason I ask is that I own a cbr1100xx it's a fine bike but I have not felt really confident on it since I bought it. It is a really heavy bike about 600 pounds and very top heavy. I feel fine on it at speed but in traffic or at parking lot speeds I start having real issues. The problems get worse with a passenger. I have taken rider training as well as a slow speed course and still. At the slow speed course even the instructor had a hard time on my bike. He let me ride the course on his HD road bike and I did ok. I would welcome some input.
