third feels much further apart on the TX300. Given that
MXA test riders complained that second and third on the
2017 TC250 were too close together, the feel of the TX300
hits the spot. Hold on. Does that make sense? Since the
ratios are almost identical, why did the TX300 feel like
it had a more usable gap between gears? The answer?
A heavier flywheel weight and different mapping. As for
sixth gear on the TX300, we never got there on a motocross track—or on the freeway heading to the track.
( 6) Electric starter. Regardless of the added weight,
we love the electric starter on the TX300. We wish the
TC250 came with it also.
( 7) ECU. The ECUs are identical on both bikes, save for
the maps that are programmed in them. Unfortunately, you
can’t switch the map out to convert your TC250 black box
to a TX300 black box. No sweat. The TX300 black box is
included in the 300cc upgrade engine kit.
( 8) Flywheel. The heavier flywheel on the TX300 gets
the power to the ground. It mellows out the powerband,
which makes it easier to work with in motion. The heavier
flywheel is something that would also add more dimension
on the stock 2017 TC250 and KTM 250SX. Contact Steahly

Q: WHAT IS THE 2017 HUSQVARNA TX300’S
A: In one word, smooth—so smooth it catches you
off guard. This is an engine that makes you feel as if you
are going slower than you actually are. The linear power-
band has no hit—and our testers like it that way. We tried
going in on the power-valve adjuster to give the engine
was harder-hitting when the power valve was turned in,
would break loose quicker, and the suspension became
more erratic because of the extra burst.
The TX300’s smooth, easy-to-ride, broad powerband gets
the power to the ground, unlike the more abrupt TC250
and 250SX. The rear end sticks like glue thanks to the
heavier flywheel and mellower ECU settings. It has the
effect of traction control. Every MXA test rider clicked
up to third gear and twisted the throttle to the stops; the
powerband did the rest. It was awesome to go fast with
virtually no effort. We will admit that our younger test
riders thought the powerband was a buzzkill. Their adrenaline gauge was set to the Clearasil setting.
Q: HOW DOES THE 2017 HUSQVARNA TX300
A: In spite of the 15 extra pounds compared to the
TC250 (due to the over-sized tank, six-speed gearbox,
electric starter, battery and kickstand), you don’t feel it as
much as you would think. We noticed the added weight in
flight and when cranking the bike over in tight turns. The
linear power helped the handling by taking the jerks and
jolts out of throttle changes. The mellow, lugging power
made for a super-smooth ride.
With the exception of the added weight, this is a very
solid two-stroke handling package. It is stable as a rock
at speed, carves through corners without a hint of understeer, and feels flat and level in the rough.
Q: HOW DID THE OFFROAD SUSPENSION
SETTINGS HANDLE A MOTOCROSS TRACK?
A: The great thing about the new AER air fork is that
you can make it as stiff as you want. The recommended
Based on the latest 250cc two-
stroke technology, the TX300
gets a larger gas tank, greater
displacement, 18-inch rear wheel,
electric start and six-speed gearbox.
