The Dunstall GS1000 CS, probably the fastest "mass" produced GS1000.

Produced with the blessing of Heron Suzuki, and listed in the Suzuki catalog.

Capable of approx. 150 mph/231 kmh.

Only a few were sold as complete Dunstall GS1000CS bike.

Additionally, approx. 200 kits (seat, cowling, brake/shifter, front fender, clipons) were sold.

The latest CS models had frame modifications, gas-flowed head with high-lift cams and stiffer valve springs, 29mm Mikuni smoothbore carbs with bellmouth velocity stacks, and the new Dunstall Power Silencers.
