that of the KTM, save for the fork guards.
Q: DOES THE TC125 ENGINE HAVE THE
SAME CHARACTERISTICS AS THE 125SX
A: If you tore the KTM and Husky engines down on
the workbench, you could swap parts to your heart’s
content, save for the clutch cover’s color and logo. But,
when you hop on the track, each bike has its own
personality. This is due to the difference in the bike’s
airboxes. The KTM 125SX’s airbox has vent holes, allowing the bike to take in big gulps of air, whereas the
TC125’s airbox could be submerged in a river without a
leak. This gives each bike a different powerband. With
the TC125’s engine gasping for air, its throttle response
and bottom-end power suffer, but the air begins to ramp
up at the end of the curve, allowing the Husky to pull a
little farther than the KTM. With increased airflow into
the 125SX engine, throttle response is heightened and
there is a significant surge in bottom-end power.
Q: WHICH ENGINE IS BETTER, THE TC125
OR KTM 125SX?
A: Although the TC125 makes more top-end power,
it takes some time to get there and, in the process, gives
up bottom-end power to the 125SX. Out of corners, the
KTM 125SX pulls without hesitation and requires minimal clutch use. Our testers even went as far as gearing
up the 125SX, going from a 50-tooth rear sprocket to a
( 5) Rims. Husqvarna specs D.I.D. Dirt Star rims, while
KTM uses Takasago Excel rims. We have had good luck
with both, but the pesky spoke by the rim lock always
( 6) Handlebars. Husky runs Pro Taper bars that are
the same height as KTM’s Neken bend, but they have
more sweep which brings them closer in to the cockpit.
( 7) Brakes. The Husky GFK front and rear rotors are
beefier than the KTM’s Galfer rotors.
( 8) Tires. The complete motocross line of Huskys come
standard with Dunlop Geomax MX52 front and rear tires,
while the KTM SX line gets Dunlop MX32s.
( 9) Clutch. Husqvarna’s clutch is equipped with a
Magura clutch lever and master cylinder, while the KTM
sports Brembo components. The Magura clutch has more
tactile engagement and the lever is an unbreakable fold
design with a more petite shape.
( 10) Frame guards. KTM’s black frame matches its
black frame guards, which run until the frame tees off.
The black Husky frame guards are much shorter. We
assume that the Husky marketing men did not want to
cover up the white frame. Guess what? KTM had a good
reason for the longer guards, as the white paint starts
to wear off mighty fast. KTM frame guards will fit
on the Husky
( 11) Seat cover. The seat cover on last year’s Huskys
should have come with a caution label. It felt as if an
entire can of Maxima SC1 had been sprayed on it. It has
been replaced with a gripper cover that is more aggressive than KTM’s rough-surface cover.
( 12) Look. All of the Husky’s plastic is different from
TC125: Share and
share alike. While the
uses the rolling
chassis of the KTM
125SX, there are
enough differences to
make a difference.
