What it is:

Sleeker styled version of Suzuki’s first big 16-valve plain-bearing four, the GSX1100. Unrivalled combination of power, torque, comfort and handling. An automatic choice for production and drag racers alike because the engine can be tuned and tuned.

Others in its family tree:

The 1100 was also available with small cockpit fairing, full fairing, and in Katana trim as an 1100 and a rare 1000.

It’s good because:

It’s very powerful very strong, was around for ages so parts availability is good, and is easily tuned. Lighter than some, too.

It’s bad because:

The electrics are rubbish. And it’s one of the ugliest things to roll off a production line. Ever.

Other alternatives:

Kawasaki GPz1100, if you throw away its fuel injection system. Buy a Honda CB1.100R if you want something for the track.
