Never owned any GS Suzuki model. But I did borrow a mates GS1000 for a test ride before purchase.
Seemed like a huge bike after my CB750 Honda. I was riding the GS along the motorway at a fair lick of speed when I caught the attention of the police in a marked Ford Escort car. Not having any insurance for the bike made my decision to F#ck Off at more speed an easy one.
At around 120mph the bike developed a central hinge in the middle of the frame! Yikes I needed three lanes of the motorway just to stay in a straight direction!
I got away, but needless to say didn't buy the bike.
