for aggressive riding, can es-
sentially be tuned to anyone's
preference, but right out of
the box, the X-Pros we rode
were dialed in perfectly for my
170 pounds when riding at a
mellow to moderate trail pace.
The 300 excels in slow, techni
-
cal environments filled with
rocks, roots, and potholes, and
when lifting might be in order.
It offers good balance and ac
-
tion but isn't exactly designed
for big jumps, large whoops,
or high-speed riding. The
same can be said for the 390.
P102 RIDE REVIEW I 2025 BETA RR X-PRO 300 TWO-STROKE & 390 FOUR-STROKE
All the X-Pro models are
tailored more for the
"average" weekend trail rider
and occasional racers.
The X-Pro 390 is
a very good "in-
between" all-around
off-roader.
(Above) The 300's counterbalanced
engine is smooth, and fueling from
its Keihin PWK 36mm carburetor
is excellent. (Above right) Both
bikes feature diaphragm clutches
that have excellent feel.
Their Nissin disc brakes are
very capable and have excel-
lent feel.
As similar and good as both
these bikes are, they are two
very different animals on the
trail. The 300 is more hyperac-
tive than the 390. The 300 is
very sensitive to bumps, reacts
instantly to rider feedback,
feels light, and keeps you on
