In late 1977, Suzuki finally joined the ranks of "1000cc club" with the launch of the GS1000, to compete with the one litre models previously launched by rival manufacturers; Honda, Kawasaki and Yamaha.

The GS1000 was based around the successful GS750; the lightest of the 750s available at the time.  Suzuki wanted a simple design, solidly engineered and of light weight.  They succeeded in their aim, as the GS1000 was only marginally heavier, at 507lbs, than its smaller brother. By lengthening the relatively short stroke of the GS750 engine from 56.4mm to 70mm, the cylinder displacement was increased from 748cc to 997cc. The power output in 1978 was quoted between 83bhp and 90bhp, depending which country the bike was exported to, thanks to differences in environmental and noise regulations. Like the GS750, the new 1000cc model was entirely conventional in having a thin wall, tubular steel cradle frame, a five-speed gearbox and chain final drive. The suspension of the big brother was more advanced, using an air and oil damped front fork, with conventional rear shock absorbers, which were replaced in May 1978 with combined gas and air units. The GS1000 was widely considered to be the best one litre, four-cylinder machine of its time.

1979 saw the launch of the limited edition GS1000S, with a small cockpit fairing; the first road going Suzuki to be sold with any type of fairing. The instrument panel was comprehensive, with the inclusion of a clock and oil temperature gauge, not to mention the bike's colour scheme, a striking white and blue livery.  Mechanical changes included an increase in rear wheel diameter to 18 inches, to increase corning (cornering??) clearance, 28mm Mikuni VM28SS carburettors and uprated suspension. Initially supplied as a European only model, huge demand from America, where Suzuki had been dominant in AMA racing, saw a limited supply of one bike per dealer released for sale in the USA.

Legendary tuners 'Pops' and Fujio Yoshimura, as well as rider, Steve McLaughlin, switched from Kawasaki to Suzuki machines for the 1978 season, winning the prestigious race at Daytona.  Wes Cooley won the 1979 and 1980 AMA Superbike Championships on a Yoshimura tuned Suzuki, and thanks to that connection, the GS1000S soon became known as the Wes Cooley Replica, although Suzuki never officially marketed the bike as such.

This 1980 European specification GS1000S is, according to the vendor, in excellent, un-restored condition, even down to the original exhaust system, which rarely survives. Originally registered in Holland, the bike is offered with a UK V5C, plus valid MoT and benefits from a recent service, which included balancing the carburettors. The Suzuki GS1000S must be one of the most desirable classic Japanese superbikes, and this is a rare opportunity to acquire one in such fine condition.
