WHAT IS IT? Even though it is called a “stem nut,” it
is really a bolt. On KTM clamps, the stem nut is just a
fail-safe since the KTM triple clamps are attached to the
stem via a pinch bolt (much like the fork-leg clamps). So,
why would Works Connection go to the trouble to make
a new stem nut? To save weight, to allow the gas-tank
vent hose to route down into it, to accept safety-wire
holes, and to be able to anodize them either black or

WHAT STANDS OUT? Here’s a list of things that
stand out with the Works Connection KTM stem nut.
(1) Vent hose. On a stock KTM, the gas-tank vent
hose is routed to a plastic elbow on the side of the head
tube gusset. When KTM was still using its quarter-turn
gas cap, there were no problems with this routing
method. But, when KTM returned to a conventional
twist-on gas cap, the vent hose would get twisted up
if the rider put the gas cap on without counter-rotating
the gas cap before installing it. The twist could actually
pinch the vent hose enough to close it off. Savvy KTM
owners took the stock stem nut and drilled a hole in
the center of it so that the vent hose could be slipped
into the stem. With this method, the vent hose could
spin with the gas cap, eliminating the twisted hose.
Works Connection’s KTM stem nut comes with the hole
machined in it. All you have to do is remove the stock
stem nut (with a 27mm wrench) and install the
Works Connection stem nut (with a 17mm wrench).
( 2) Size. The stock KTM stem nut is enormous. To
allow for more room to get a wrench on it, Works
Connection downsized the hex head from 27mm to
17mm, which is exactly what KTM did on the 2014
450SXF Factory Edition III. The 2061-T6 aluminum nut is
lighter and easier to access.
( 3) Overlap. The 30mm-wide Works Connection
stem nut has the same overlap on the top clamp as the
Factory Edition III, which is 4mm less than on the stock
34mm-wide stem nut. The Works Connection stem nut is
only tightened to 9 foot-pounds.
( 4) Safety wire. Every factory bike is equipped with
safety-wire holes. Works Connection added them to their
stem nut just in case you want to channel your inner
WHAT’S THE SQUAWK? Two quibbles: (1) The vent
hose might be tough to push into the stem hole at first,
but that is just because it was bulged out by being
wedged over the plastic elbow. It will fit easily after a
few uses. ( 2) Often the bottom of the steerer tube is
blocked by the front fender. If it is, drill a hole to vent it.
The Works Connection stem nut solves a minor
problem, but one that rears its ugly head every
time you put gas in your bike. The frequency
of the irritation makes the Works Connection
stem nut a four-star product.
