Kawasaki KR250 Gallery
Kawasaki designer Nagato Sato started
work on the first KR twin during 1974 adopting an
inline layout in order to minimise the width and thus
the frontal area of the machine whilst still being
able to utilise disc valves. The liquid cooled engine
was housed in a conventional twin loop steel frame
with twin rear shock absorbers. The machine first
appeared in competition during 1975, often with Mick
Grant in the saddle continuing into 1976. These years
brought little in terms of success, but provided a
wealth of information and the opportunity to develop
the fledgling racer. 1977 marked a turning point for
the twin and Kawasaki when Mick Grant secured the
firms first Grand Prix win in the 250cc class at the
Dutch TT at Assen and followed that success with a
win at the Swedish Grand Prix later the same year.
That racer heritage shines through in
the street KR250. The engine pulls cleanly everyplace,
but it's happiest between 8000 and 10,500 rpm. When
the engine hits eight grand at full throttle in first
gear, the front wheel claws for the sky while the
KR leaps forward almost as quickly as a catalyst-equipped
RZ350 Yamaha. And the Kawasaki cruises smoothly and
effortlessly at speeds unheard of for a 250: 80, 90,
100 mph. Top speed is well over 110 mph. The penalty
is that, much like a racing 250, the KR only makes
good power in one gear at any given speed. Come out
of a corner a gear too high, the engine will drone
ineffectively.

The machine offered was purchased from Jean
Francois Balde, who campaigned it during the
1981 Grand Prix season, securing second place
in the championship and a Grand Prix win at
the first Grand Prix of the season in Argentina.
The KR twins had benefited from revised porting,
redesigned expansion chambers, the adoption
of separate cylinder's and heads and an increase
in carburettor size to 34mm by the 1981 season,
which as the results demonstrated, enabled the
Kawasaki's to maintain their dominance of the
250cc Grand Prix class.

Handling-wise, the KR is quick-steering yet
stable, and the suspension is supple over small
bumps, rather harsh over large ones. The only
real handling defect, however, comes from the
slightly rearward weight bias: The front end lightens
so much under power that the steering can be vague
and imprecise when charging out of slow turns. |
