MY Suzuki GT 550J wasn't as fast as its big brother but it was a perfect compromise between the GT 380 and GT 750. The low-mounted exhaust pipes decreased the ground clearance significantly in the curves and the the suspension was quite soft but othervise the GT 550J was smooth, fast and durable. The Suzuki engineers had done a fine job with it.
