||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.
