This is how we set up our 2017 Husqvarna TC125 for
racing. We offer it as a guide to help you find your own
WP AER AIR FORK SETTINGS
First, focus on balancing out the bike for your weight
by adjusting the air in the forks. If the forks are diving
into the corners, go up a few psi. If they tend to be
rigid and push out on the entrance of corners, drop
the psi down a few points. For riders between 155 and
170 pounds, we ran 123 psi. Riders 170 to 200 pounds
favored 125 psi. Once the pressure was set, all the riders
went softer on the compression. The forks have good
bottoming resistance, so going softer for a plusher ride
is not an issue. For hardcore racing, we recommend this
fork setup on the 2017 Husqvarna TC125 (stock settings
Compression: 20 clicks out ( 15 clicks out)
Rebound: 11 clicks out ( 15 clicks out)
Fork-leg height: Stock
Notes: The fork spring rate is light because of the
target weight of the typical 125/150 rider. If you are
heavier, don’t worry; the WP suspension has enough
adjustment to accommodate you. Lighter riders can turn
the compression clicker out to get the feel they want.
WP SHOCK SETTINGS
The rear shock was in the ballpark for the majority
of our testers. For hardcore racing, we recommend this
shock setup for the 2017 Husqvarna TC125 (stock specs
are in parentheses):
Spring rate: 42 N/m
Race sag: 108mm (110mm)
Hi-compression: 2-1/2 turns out ( 2 turns out)
Lo-compression: 12 clicks out ( 15 clicks out)
15 clicks out
Notes: The stock shock settings are in the ballpark.
We ran slightly less sag than what Husqvarna recommends (110mm) but more sag than what we ran with
the KTM 125SX due to the Husky’s taller seat height.
MIKUNI TMX 38MM JETTING SPECS
Here’s what we ran in our 38mm TMX (stock settings
are in parentheses).
Main jet: 480
32 ( 45)
Air screw: 1 turn out (1-1/2) ❏
The powerplant of the TC125 pumps out close to 38 ponies.
That is as much as the 250F bottom feeders.
The new WP AER 48mm forks are the bee’s knees. They are
simple, supple and have firm bottoming resistance.
A: Husqvarna isn’t fooling anyone. It is still just a
KTM with a fake mustache and dark sunglasses. We are
among the buying public who want these two products
to be differentiated from each other. We accept that KTM
wants to maximize the economy of scale that comes from
already building engines, forks and frames, but nevertheless, we expect a Husqvarna to have something special to
build customer loyalty. Still, it is hard to ignore how good
the Austrian twin 125cc machines are. We adore the entire
package. From the chassis to the plush suspension to the
potent powerplant, this is a great machine for anyone getting off a minicycle or for those riders who like to twist the
throttle to the stops.
