I bought a Virago 2001 for my wife. She complained it beeing very unstable.I tested for a few days, and I agree. It´s turning very easily, but to steer back straight again is much much harder. This makes even a small turn feels very strange. Also driving straight forward, it´s very nervous, and the slightest scratch on the road makes the bike do some maneuver to the left or right. Tips?
