the CVT belt too, so the use of low
gear comes into play more than normal. Power steering is highly recommended as well. The cost of Moapa is
a bit heavy too, at $228 per tire.
However, that’s a small price to pay to
never have to worry about being
stranded by a flat tire. These tires are
so tough, you can hardly tell if you
were riding on a punctured tire.
Traction was awesome as well. They
clawed through the loose dirt and
tacky soil well. Mud clean-out was
fair, and they rolled very smoothly on
hardpack. For normal high-speed
riding, we would not choose the
10x28 sizing by choice, but they did
wonders for stability and ground
clearance. We plan on putting more
time on these 12-ply Moapas under
our RZR XP 900 in the near future.
To stay on top of any CVT issues that
may come up, we installed a complete
$1500 clutch package from STM
Powersports. The package contains a
very adjustable primary clutch, sec-
ondary clutch and helix. Also included
with the kit was a selection of weights
and adjustment pins for tuning the sys-
tem. We tried the STM products with
the massive 28-inch DWT tires and
with the 26-inch stockers.
The STM product is a work of art.
The CNC-machined pieces look like a
prize-winning sculpture that was built
by a high-tech robot. Its details are so
cool-looking, it’s a shame it has to be
hidden by the CVT cover. A clutch
package this sophisticated are gener-
ally reserved for highly modified
engines. In our case, we may build the
engine in the future, but for now, we
The Rok’N Lock wheels from DWT
are built not only to keep the tires
beadlocked to the wheel, they help
keep debris from entering through the
wheels and hanging up on the brake
caliper. The wheels proved to be just as
tough as the 12-ply tires.
