Q: FIRST AND FOREMOST, IS THE 2016 KTM
150SX BETTER THAN THE 2015 KTM 150SX?
A: The 2016 KTM 150SX is all new from the ground up
and shares very few parts with last year’s 150SX. The 2016
KTM 150SX’s handling, suspension and engine characteristics are a night-and-day difference from the 2015 models.
Q: WHAT CHANGES DID KTM MAKE TO THE
2016 150SX CHASSIS?
A: When KTM developed its 2016 motocross line, it
made the decision to update every SX and SXF model (save
for the KTM 250SX). Thus, every transferable modification
that the KTM engineers made to the 450SXF they made to
the 150SX. But, because of the unique nature of a two-stroke
versus a four-stroke, there were updates to the KTM 150SX
that were quite a bit different from the ones made to their
bigger brothers. Here is a list of chassis updates.
(1) Frame. The chromoly steel frame has been lightened
and provides 20 percent more torsional rigidity and 30
percent less longitudinal stiffness.
( 2) Geometry. The head angle has been steepened by
0.4mm and the wheelbase shortened by 10mm.
( 3) Paint. Back in 2015 KTM granted our wish, and the
wish of the vast majority of KTM owners, by painting the
frame orange. For some Scrooge-like reason they dropped
the orange in 2106.
( 4) Subframe. The aluminum subframe is smaller and
20 percent lighter.
( 5) Swingarm. To the naked eye the 2016 swingarm
looks the same as the 2015 model, but the internal structure
has been revised to match the flex characteristics, and it is
( 6) Footpegs. The all-new footpegs are a work of art.
They are self-cleaning to reduce dirt build-up in the hinge
for optimum function in the worst conditions.
( 7) Triple clamps. The offset remains the same (22mm),
but the handlebars are now rubber-mounted to reduce
vibration at the handlebars.
( 8) Airbox. The no-tools airbox has been updated to be
even simpler, and the filter is the first-ever plug-and-play
design. It’s impressive.
( 9) Fork settings. The quick-adjust WP 4CS fork settings
have been updated and use softer springs (from 4. 4 N/m to
4. 2 N/m).
( 10) Shock. The 150SX gets the latest-generation WP
shock. It features a revised reservoir, new piston, new
shock shaft and new clevis design that shortens the shock
length by 12mm. The linkage is also an all-new design to
fit the architecture of the new frame.
