RetroSBK’s GSX-R1000-based Yoshimura Suzuki GS1000 tribute

Remember Wes Cooley and the Yoshimura Suzuki GS1000 on which he won the AMA Superbike Championship in 1979 and 1980? While the GS1000 was first made in 1977, Suzuki later produced a special model – the GS1000S – in tribute to Cooley’s race wins aboard the Yoshimura-fettled GS.

With around 87 horsepower, tuner-friendliness, reasonable handling and a generous helping of reliability, the Suzuki GS1000 was the seminal sportsbike of the 1970s. By the standards of that era, the GS’ air-assisted forks, steel tube chassis and twin brake discs at the front worked very well indeed. And Cooley’s spectacular racing style, coupled with all those race wins, made the big GS lust-worthy for most sportsbike fans in those days.

More than thirty years have passed since the GS1000 first came out, but the bike hasn’t been completely forgotten just yet. Take William Kenefick, of RetroSBK, who’s built the modern-day equivalent of a GS1000 that you see here. Based on a 2008 GSX-R1000, the bike has, according to the RetroSBK website, been built in tribute to Hideo ‘Pops’ Yoshimura’s contribution to production-based roadracing in the United States.


In spirit, RetroSBK's tribute remains faithful to the original

Unfortunately, the RetroSBK website doesn’t seem to have William Kenefick’s email ID, so we couldn’t write to him and ask for more details. But according to whatever little information we could glean from various bike forums, the GSX-R1000-based GS-tribute took over 400 man-hours to make! The tail unit, fuel tank and chassis are stock GSX-R items, a full Yoshimura exhaust system has been installed, various carbonfibre bits have been bolted on, and then of course there’s that custom-built 1970s-style fairing.

There’s also a new Ohlins shock at the back, the front fork’s internals have been reworked by RetroSBK, the Brembo brakes have been uprated to race-spec components and power output is a claimed 178bhp at the rear wheel. Amazing stuff, eh? Oh yes, we love this bike…!
