Hey, I'm 47 years old, and wish I had my '82 GPZ 550 back that I purchased new. Now years later, kids grown I find myself commuting 40 miles one way to work (at least in the summer) on my old 440. I've been looking for a "standard" bike and spotted the Ninja 500R. How is it compared to my old GPZ for power, handling, torque, etc? I really liked the old 4 cylinder scooters of the 80's but need something newer and reliable. How is it for smoothness? (I'm gettin' old). Thanx.
