Suzuki GS250 T
1983 suzuki gs250 fw
every once in a while, some motorcycle company decides to find the smallest engine displacement that can be divided into four cylinders. honda did it in 1973 with the cb350f, benelli responded a few years later with its 250 quattro, and now there is the suzuki gsx250fw. suzuki's little four is a technical marvel of sorts. the four-stroke, double-cam, liquid-cooled, 249cc mini-motor has 44mm pistons traveling through a 41mm stroke. just how big is a 44mm piston? three of them could fit into a honda xl600 cylinder without touching each other or the cylinder wall. but even engineers hell-bent for miniaturization couldn't bring themselves to put four itsy-bitsy valves in a space well under two inches in diameter, so the gsx makes do with two valves per cylinder. gallery
