The model that Graeme arrived with was
a K75C, a lighter three-cylinder version of
the K100, introduced in 1986, with a 750cc
motor producing 75bhp. An American
motorcycle journal reported, “they [the
K75s] were instantly highly rated, and
favourably reviewed, compared to the
heavier, hotter, and at the time, more
vibration prone 4-cylinder big brother
K100”. Although the bikes were essentially
the same, the loss of one cylinder reduced
the weight of the K75 by around 23kg.
Riding behind a K75 it’s possible to identify
the smaller bike by the muffler which is
triangular for three cylinders, instead of
square indicating four cylinders, as on the
bigger bike.
Graeme bought the K75C 18-years ago.
It’s a 1987 model. The bike has clocked
up 148,036 kms. Graeme reports “Tyres,
batteries, and plugs have been replaced
several times, and the only mechanical
problems have been usage predictable;
clutch plate, fork seals, rear shock, and
front discs. Any other problems seem to
be relatively minor and predictable. After
25-years, the plastics in the handle bar
switch blocks began to fail, so I replaced
them.” This is certainly an impressive record
for a 32-year old bike, and it is not, I can
say with a degree of authority, a classic
trophy that is kept only for sunny Sunday
afternoons.
