eta says its all-new-from-
the-ground-up 450 RX
motocross bike has been
in the works for more than four
years, but now it's here and
is expected to be available to
the public in December with a
$10,999 MSRP.
Beta, a company known
more for its trials and enduro
motorcycles, says the 450 RX's
fuel-injected four-stroke engine
has been designed specifi
-
cally for motocross. The
counter-balanced
four-valve engine
uses a five-speed transmission
with a hydraulically operated
diaphragm clutch that Beta
says has three adjustments "to
obtain that perfect balance of
grip and progressiveness." The
engine is also fitted with two
specific engine maps (for wet
and dry conditions) and four lev
-
els of traction control. A button
on the handlebar controls both
engine mapping and TC levels.
The lubrication system uses
separate compartments for
engine and transmission oil.
The engine resides in a steel
frame with an aluminum sub
-
frame. The air filter is serviced
via a quick-access side panel,
and the seat is easily removed
via a push button. Fuel capacity
is 1.8 gallons.
The 450 RX uses Kayaba
suspension components, which
includes a 48mm fork. Both fork
and shock are fully adjustable.
Nissin handles braking. Beta
says, "The front brake caliper is
a smaller, more modern design
and provides the latest in brak
-
ing technology."
Claimed dry weight is 229
pounds.
