Suzuki’s first-generation 250c four-cylinder, the GS250FW, might have been underwhelming, but if at first you don’t succeed… The GF250S was the next step and a marked improvement, with 16 valves and 45bhp, making it look much more like a viable rival to the dominant 250cc two-stroke twins it was up against. But the pace of development in the 1980s was relentless, and a mere 12 months after the GS250S appeared, Suzuki launched a ‘proper’ GSX-R250, complete with aluminium beam frame and full fairing, consigning the GF250S to the history books.
