or a larger countershaft sprock-
et, or some kind of combination
of both. If this were my bike,
I'd experiment with gearing.
Beta markets the RX 350 as a
motocross bike that can also
be ridden recreationally with
vets in mind, who like to rail the
outside lines at a lower rpm,
which might explain the "univer-
sal" stock gearing and trying to
appease both types of riders.
Overall, this Beta is a ton of
fun to ride because it doesn't
fit the mold. It's a modern big-
bore two-stroke with personal-
ity that reminds us of those
classic 500cc monsters but is
much easier to manage. With
newcomers like the Kawasaki
KX327 soon entering the ring,
the Beta RX 350 finds itself at
the center of a modern-day bat-
tle for two-stroke supremacy.
