The Suzuki Burgman 650 was purchased for my wife as an anniversary gift. When we picked it up, she asked me to ride it home for her, until she could get used to it. Traveling north on I-75, I found myself doing 100 MPH, without realizing it. The scooter/bike has plenty of power and comfort on the freeway. As well, it is nimble and easily maneuverable through city traffic.
This scooter/bike (I call it a scooter/bike, because you can't really call it a scooter, in the conventional sense) is like a cross between a Honda Gold-Wing, a bullet bike and a scooter, which is a weird, but wonderful combination.
The seat is comfortable and is designed for long trips. My wife has ridden many motorcycles of all shapes and sizes, being that we're a motorcycle family, but she says that hands down, this is her favorite. As long as it's above 50 degrees in the morning and not raining, she's riding it to work.
As far as balance is concerned, it's the most balanced machine I've ever ridden. Praising this machine isn't easy for me, basically because I've always looked down my nose at scooters. The Suzuki Burgman 650 has definitely changed my mind.
