The MX32 covers soft to inter-
mediate terrain, while the MX52
excels in intermediate- to hard-
terrain conditions. The Geomax
began life as a top pro race tire
and, with input from the AMA
Pro Supercross and Motocross
racers over the past few years,
Dunlop was able to develop an
all-new tire and now makes them
available to the public.
Used by racers such as Ryan
Villopoto, Ryan Dungey, James
Stewart and Ken Roczen, the
prototype version of the Geomax
MX32 and MX52 front and rear
tires have already piled up 62
overall wins, 55 holeshots and
187 podiums in AMA MX and Su-
percross, according to Dunlop.
Both the front and rear MX32
and MX52 share the new Dunlop
design features. Dunlop's new
patented Progressive Corner-
ing Block Technology (PCBT),
or "block within a block" design,
is said to give more progressive
cornering action and aid in slide
control. For a smoother ride, en-
hanced feel and improved cor-
nering action, Dunlop used an
Enhanced Carcass Tension Con-
trol System (CTCS), aka "tuned
carcass flexibility," from recesses
placed along the tire carcass. A
redesigned sidewall construction
with a controlled rebound rubber
element is said to help "damp
out the bounce" to give the tire a
better flow with the track surface
and improve feel through the
whoops.
Exclusive to the MX32 line is
the multiple block distribution
and varying pitches and angles of
the rear tire blocks and staggered
middle blocks and alternating
mid shoulder knobs of the front
tire, both aimed at increasing grip
and feel. The Chiseled shoulder
block of the front MX32 increas-
es overall side grip. The elimina-
tion of the tie-bar design in both
of the MX32s is said to improve
feel and performance in sandy/
muddy conditions. The MX52
rear you'll see staggered center
blocks in order to spread the load
and help with impact dampening
and stability. The MX52 front fea-
tures a unique tread block distri-
bution with knob design, pattern
and knob construction made to
work in one direction for added
feel.
On the track we were im-
pressed with the overall feel and
increased traction of the MX32
and MX52 over the old Geomax
models. We started out with the
MX32 front and rear combo,
which feel very connected to the
track even providing a smoother
ride especially up front where
you felt less feedback in the
bars. The amount of traction was
impressive in both soft and hard,
as well as freshly watered hard-
packed surfaces, as we experi-
enced minimal slide and traction
loss. The tire had a solid feel and
a predictable ride, boosting the
