WHAT IS IT? An aftermarket shock linkage that not only
alters the starting point of the rising rate, lowers the seat
height and stiffens the shock’s initial stroke, but is also
adjustable and acts as a skid plate for the shock linkage.
WHAT’S IT COST? $299.95.

WHAT STANDS OUT? Here’s a list of things that stand
out with the Fastway linkage guard.
(1) Linkage theory. In its simplest form, a shock
linkage compresses the shock from the bottom while it
is being compressed from the top by the energy of the
bump. What is typically ignored is the effect a shock
linkage has on the bike’s chassis. MXA test riders have
always been concerned about tall seat heights and
stinkbug chassis angles. Historically, we have used
longer shock links to stiffen the initial part of the linkage’s
rising rate curve (they don’t change the rising rate, just
its starting point), balance out the front and rear of the
bike (which helps in setup) and, finally, to lower the seat
height (so we can slide the forks up and down in the
triple clamps to tune the handling).
( 2) Numbers. Fastway’s linkage guard can be set up
to the stock length, 0.5mm longer, 1.3mm longer or 2.0mm
longer. The Fastway link can lower the seat height of
your bike by 20mm.
( 3) Handling performance. You might think of the
Fastway link as a suspension device, but the MXA
test crew believes that it is most useful as a handling
device. Lowering the rear of the frame kicks out the
head angle, which can then be set across a wider
window by raising and lowering the fork height. As
the overall chassis height moves down, the cornering
improves enough to calm down any twitchiness.
The longer link allows the rider to adjust the handling
by changing the fork damping, fork leg height and
( 4) Suspension performance. The longer linkage
arms rotate the bell crank deeper into its stroke, which
translates into stiffer initial suspension. The result is a
much more balanced chassis; the rear suspension stays
higher in the stroke and has more usable travel, and
the setup options are increased.
( 5) Guardian. The MXA gang hangs out with lots
of offroad, endurocross and desert riders who believe
wholeheartedly in the Fastway linkage’s ability to
protect the shock linkage from damage.
WHAT’S THE SQUAWK? Two quibbles. (1) Price.
At $299.95, it is about $20 more expensive than a
Joe Gibbs Racing adjustable link and $50 more than
comparable non-adjustable links. ( 2) Weight. It adds
about 7 ounces to the weight of your bike.
Every MXA test rider prefers
FASTWAY ADJUSTABLE KTM LINKAGE GUARD
the 2015 KTM with a longer link. The
price is justified by Fastway’s four-way
adjustability and linkage guard capabilities.
