During the 1972
Yamahaãs works riders campaigned machines
in the 250 and 350cc classes that utilised liquid
cooling and which acted as prototypes for the
following seasons production racers.
The liquid cooling
employed on the new TZãs sought to address
the Achilles heel of the TR3/TD3 air cooled
racers ¹ their propensity to nip-up and
established a line of of racing machinery whose
success is unparallelled in motorcycle road
racing. The A series models newly developed
engine was housed in a set of cycle parts that
were essentially the same as those employed
by the previous aircooled racers with drum brakes
and twin rear shock absorbers. The subsequent
years B series machines continued in much the
same way, however a major revision occurred
1976 with the introduction of the C÷
series.
The new models
employed a monoshock rear end and front and
rear disk brakes. The engine had benefited from
the ongoing development of the works supported
bikes resulting in the 250cc producing 52bhp
whilst the 350cc machine had gained 4bhp. Subsequent
development was limited to detail changes until
the the much needed introduction of the F in
1979, a consequence of Yamahaãs R&D
resources being committed to the development
of new road models, partly in response to tighter
emission controls and partly as a result of
their battle with Honda for supremacy in the
market place.
Yamaha also produced
a limited number of TZ50 production race bikes
between 1990 and 1991 specifically for use in
a Japanese National Championship. Subsequently
a very limited number of the machines were exported
to the United States and Europe.
