FIRST LOOK I 2025 BETA 300 RX & 450 RX MOTOCROSSERS
B
eta's two motocross models, the
300 RX two-stroke and 450 RX four-
stroke, feature updates that the com-
pany says "enhance both models."
Updates to
the 300 include changes to
the engine, chassis and suspension. A new
frame highlights the 300, which Beta says
is now more like the 450 RX's frame. The
main benefit is improved turning. There is a
new aluminum subframe that also houses
a more compact plastic tray system for
the battery and starter solenoid.
Beta says that updated porting
specs
to the engine give the 300 more power,
making it "pull harder and longer."
The 450 RX gets a stronger rear alumi
-
num subframe, redesigned airbox, suspen-
sion upgrades, as well as a more powerful
lithium battery,
among other changes.
Engine mapping has been updated
with the latest settings that have been
tested
by the Beta race team. It also has
traction control.
Both bikes will be available in October
with MSRPs of $9499 for the 300 RX and
$10,999 for the 450 RX.
