TX300 INTO A TC300
The 2017 Husqvarna TX300 is like a motocross bike with a kickstand, 18-inch rear wheel, over-size fuel tank, heavier fly- wheel, electric starter and a semi-wide-ratio transmission. It’s
a good all-around off-road bike, but the MXA wrecking crew wasn’t
interested in the bike for its ability in the woods. We wanted to
unleash its motocross potential. Neither Husqvarna nor KTM produces
a motocross version of their 300cc two-stroke machines. We wanted
to rectify that by taking apart a TX300 and putting it back together
again in full motocross regalia.
EVERY RIDER FROM BEGINNER TO PRO
FELT THE TC300 HAD A VERY USER-
FRIENDLY ENGINE. THEY DID NOT,
HOWEVER, COLLECTIVELY CHOOSE THE
TC300 ENGINE OVER THE TC250.
To be transparent, Vets and Novice riders did not fare well with the
all-new Husky TC250. Riders spoiled by the easy-to-use, planted feel
of four-stroke power were caught off guard by the explosive TC250
muscle. Instead of twisting the throttle and the rear end sticking
to the ground, the TC250 felt like it was lifting up and blasting off.
The TC250 was a wild ride that our Intermediate and Pro test riders
adored, but for everyone else there had to be a better combination
of power and usability than the standard-issue TC250. We are not
backpedaling on our glowing opinion of the TC250. It is the best
250cc two-stroke on the market (alongside its twin brother, the KTM
250SX). It has great power, handling, suspension, brakes and clutch.
So, what gives? We wanted to build a two-stroke that was easy to
ride, had a broad powerband, and got the job done without all of the
Cape Canaveral fireworks.
Since we had a TX300 and wanted a TC300, this is how we got one.
(1) Kickstand. A kickstand on a motocross track is just added
weight. Either way, you will still need a bike stand to check spokes
and tire pressure, change wheels and lube the chain. If you don’t like
picking your bike up to put it on the stand or have trouble doing so,
look into the Power Lift motocross stand that many of our testers have
grown to love.
( 2) Rear wheel. The TX300’s 18-inch rear wheel gives the bike
some added plushness in a straight line but starts to fold over in flat
corners. The rear end wallows under acceleration with the 18, so we
changed it out for the more consistent and familiar feel of a 19-inch
( 3) Gearbox. The final ratios between first through fifth on the
TX300 are similar to the TC250’s gearbox. The TX’s semi-wide-ratio
transmission is better—and worse—than the TC250’s. It is better in the
sense that there is a larger gap between second and third gear. With
the TC250, second and third are too close, which makes for awkward
shift points. It is worse due to the big gap between third and fourth,
