Tachometer
and
Speedometer
With the
increase
in speed
of
the motorcycle,
the vibration and also the
vibrat ion
transmitted from
the
road
surface become greater.
If
this
vibration
is
transmitted
directly to
the
tachometer, the control
spring
wi
ll set
up a resonance, and the shaft wi
ll
be exposed to excess wear and
the
indicator needle
will be subject to oscillation.
For this
reason,
the
CB
450
and CL 450
tacho-
meter and speedmeter hove been
designed
light
in
weight to minimize
vibra
tion
and
further, the
meter
cases are made of synthetic
material
(ABS, acrylic
resin)
to
furt
her
absorb
any residual vibration.
The speedmeter is
of
a magnetic coupling of a
needle
indicating
type.
The rotation of
the
wheel
is transmitted by
the speedometer shaft
to the
speedmeter in the definite ratio of
the
wheel
speed.
The
tachometer
also
of
the
magnetic coupling
needle indicating
type.
The rotation
of
the camshaft
is transmitted in
definite ratio by
the
tachometer
cabl
e
to the
tachometer.
