A Gigantic, Water-Cooled
Two-Stroke Makes Its Debut
At The Japanese Motor Show
ONE OF THE EYEPOPPINGEST ma-
chines to be seen in a long time
was unveiled by Suzuki at the
17th Tokyo International Motor Show.
Behold the wondrous 750. powered
by a transverse, three-cylinder, two-
cycle engine, in unit with a five-speed
transmission. No horsepower figures
were given, but if you study the Titan
500 which has 46 horsepower, divide by
half, and add that onto 46, that gives 69
plus with maybe five or six more
thrown in for the water-cooling and
electronic ignition. Seventy-five horses
sounds about right. You can bet it
won’t be much less, for Suzuki knows
they will have to build a screamer to
flee from the swiftest. Honda Four and
Mach Hl.
The vitals: three carburetors fitted
with short rubber tubes onto the engine,
feeding mixture through a piston-port
induction system. Lubrication by Suzu-
ki CCI. A capacitor discharge electronic
ignition system, similar to the ignition
on Suzuki racing cars. And kick starting,
which shows that Suzuki has a lot of
faith in their cdi to fire up before your
leg wears out.
The most unique feature of the
engine is the water-cooling; this is the
only water-cooled motorcycle to appear
since the famous Scott two-strokes of
the late 1930s. A polished aluminum
water jacket surrounds the three cylin-
ders, and is cast with rows of stubby
vertical fins for what could strictly be
called an air/water cooling system.
Short intake and exhaust stubs are also
cast on the cylinders. Coolant is circu-
lated through a small radiator set in
front of the engine. An electric fan is
enclosed in a small shrouding behind the
central part of the radiator; presumably
it is switched on automatically at a
certain critical engine temperature (as
when idling too long or moving in slow
stop-go traffic).
The engine exhausts through three
pipes; the right and left pipes fit into
huge mufflers that end with black re-
verse taper cones. The center pipe is
siamesed at a point under the engine
and feeds into two smaller mufflers.
Their total volume is supposedly equal
to that of one of the big ones. The
reason for the split exhaust system for
the center cylinder is said to be the
symmetrical styling it allows on the
machine. Indeed, the swept-up angle of
the pipes does seem to resemble the
Honda CB75O. generally regarded as a
styling standard in Japan.
The exquisite engine is carried in a
twin-cradle frame of broad beam and
sturdy gusseting. Large webs at the
point where the downtubes meet the
top rails provide further reinforcement...
