Installation Instructions
Fits: Kawasaki 1992-up KX80/85/100 & Suzuki 2003-up RM100.
(Including the big wheel model)
Lowers Rear 1 3/4"

1) Before removing the OEM
links, take a race sag measurement (amount of vertical movement
of
the rear axle FROM no weight to bike weight plus rider weight) with rider
in full riding
gear,
standing on the pegs. The race sag recommended by Kawasaki is 3.25 to 3.50
inches
and
if the same sag is used with the KoubaLinks they will lower the rear 1
3/4 inches. These
longer
links put more leverage on the rear spring, so bear in mind the race sag
may need to
be
reset after the longer Kouba links are installed and our recommended race
sag with the
new
links is 3.0 to 3.25 inches for the best performance. With our sag recommendations,
the
rear
will not be lowered the full 1 3/4 inches but will ride smoother on the
small stuff and
have
more travel remaining.
2) Raise the motorcycle
with a bike stand, milk crate, etc., so the rear wheel is just slightly
off
the
ground. Remove the 17mm nut (right side) from the forward link mounting
bolt and
push
it out the left side. *You may need to raise the swing arm slightly so
the bolt will slide
out
freely. Then remove the nut off the rear link mounting bolt (left side)
and push it out the
right
side. Both links will now be off and your ready to install the KoubaLinks.
Some bikes
have
both the link mounting bolts installed from the same side and can see no
reason they
cannot
be installed from either side.
3) When installing the
KoubaLinks, (engraving to the outside and readable from the right side)
the
left link engraving will read backwards, as both links are identical. Install
the new links
in
the reverse order of the removal and torque the link mounting bolt nuts
to approx.
40
lbs-ft.
4) After the links are
installed, reset the race sag. If the links are for lowering purposes
ONLY,
sag
can be set at 3.50", and will lower the rear of the bike approx. 1 3/4
inches depending
on
the axle adjustment. If the best performance is desired we recommend a
race sag
setting
of 3.0 to 3.25 inches. The easiest way we have found to adjust the
rear spring
preload
is to use a long punch (we use a piece of 1/4" X 12" steel keyway stock,
rounded
on
one end) to loosen the top jam nut from the right side, then grasp the
spring at the
bottom
and turn the spring and the preload nut at the same time. Turning
the spring/nut
clockwise
increases the preload and decreases the sag. Do not forget to tighten
the jam
nut
with the punch after setting the sag.
5) The front forks can
be slid up in the triple clamps until they almost contact the handlebars,
which
is a good starting point with the lowering links. Headshake or turns
too quickly?
Move
them back down a little, like 1/8" at a time until handling is exceptable.
Disclaimer:
Sliding
the tubes "up" farther can allow the tire to hit the fender and could lock
up the
front
wheel, so be careful out there.
