VOLUME ISSUE FEBRUARY , P87
while we could hardly feel a dif-
ference on the 300s we have rid-
den lately. So that is nice, and you
also have the option to adjust the
powervalve spring preload, which
can make a massive difference
in the power delivery. Tightening
the powervalve spring will keep
the powervalve closed longer and
mellow it out.
The clutch performance was
good, with no issues. The hydrau
-
lic actuation is smooth and has
a reasonably light pull. The same
can be said for the Nissin brakes,
which have plenty of power and
are predictable.
We never had an issue with
overheating on the 250 RR, but if
you are taking on extra tough trails,
we suggest adding a cooling fan.
(Beta offers a fan kit for $210.)
None of the Austrian 300 two-
strokes come with a cooling fan
either, however, models from the
French manufacturer, Sherco, are
fitted with cooling fans.
The Beta RR chassis is versatile
and works well on tight trails in
the woods. It also feels balanced
and predictable in faster desert
sections. Some test riders have
noticed that the turning radius is
slightly wider than that of other
The Beta RR two-
strokes use an oil
injection system, so
you don't need to
mix your fuel. The
Race Edition models
ditch that system in
favor of weight, but
we find that most
trail riders prefer not
to mix their fuel.
