The latest White motocross racer is unusual in
several respects, not the least of which is the name.
Cycle World rode this machine when it was in the pro-
totype category. And now, more than a year later, it is
back as a full production scrambler for sale to the gen-
eral public. The Tornado comes in a wide variety of
models. Our test bike was the “class C” version, but had
knobby tires in place of the AMA class C tires, normally
fitted to this model.
A low level expansion chamber is used on the class
C model, and this is a bit of a puzzle, as it hangs out too
far on the left for dirt track racing. It is partly due to the
oval cross sectional shape being set horizontal, rather than
the more usual vertical arrangement. To further confuse
the issue, the foot pegs are of a non-folding variety. In
fact, one might say the pegs are among the least folding
we have seen for some time; it would take something like
a truck to bend them. So as long as one is not racing
class C, and folding pegs are not required, there is the
feeling that you will have some place to put your feet
after the machine has been dropped. However, folding
pegs are available from the distributor.
The engine is a straight forward two-stroke single,
having equal, or “square” bore stroke measurements, a
rather standard arrangement by today’s design. Cylinder
and cylinderhead finning are unusually massive, giving
the appearance of a larger displacement engine. These
castings, as well as the crankcases, are quite rough exter-
nally, the actual crankcase is highly polished to assist gas
flow. Flywheels are highly polished and do not have bal-
ancing holes. In order to compensate for reciprocating
weight, the flywheels have a flat on the crankpin side.
This has the same effect as drilling holes, but is a much
cleaner arrangement...
