Domestic type (Japan)
In the domestic market, 30 of them coloured loswhite were sold,
all the others were tricolour.
This picture shows a tricoloured one.
This picture was used in the catalogue.
(wouldn't you like to get a poster of
this, eh?)
This picture shows a domestic type (Japan)
stripped of it's body work.
You can tell that this is a tight little
package because
the front tire and the radiators are placed
unusually close.
The handlebars and instruments of a domestic
type
The handlebars are slightly wider apart
when compared to NSR250R, 1988.
The cams and crank were newly designed
for RC30.
Cam gear train, an original design of
Honda's, is a method to provide
direct drive to the cam shaft by gear,
rather than using chains.
(special two gear drives and cam shafts
that ran in reverse were used on the work's racers)
The con rod is made of titanium alloy.
This was the first production motorcycle
to use titanium alloy.
It is an expensive part which costs nearly
30,000yen.
The carburettion is provided by four 38mm
Keihin's
sitting in two banks, of two between
the V-4 cylinders.
Stainless steel exhaust pipe and silencer
of
large capacity. Durability is ensured.
The engine cooling system consists of
two radiators and two cooling fans equipped
only on the upper radiator. This seems
very effective, but only when driving at 60km/h or faster.
The water temperature will not drop below
90 degrees Celsius. Avoid riding in cities.
Even during the cooler months, when caught
in a traffic jam, the fan will not do enough and you WILL over heat.
(If you think that by changing to the
much larger HRC race rads you can correct this, think again.
Yes they are much larger and because they
are you have to remove the fans.
So the result is better cooling at high
speeds but no cooling when your stopped.)
Stopping power up front provided by
dual 310mm floating discs with four piston calipers.
The 43mm cartridge style front fork uses
quick release axle clamps.
This enhances the readiness of tire exchanges
during durability races.
