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)
rider in full riding gear, standing on the pegs. The race sag recommended
Kawasaki is 3 to 3.25 inches and if the same sag is used with the KoubaLinks
will lower the rear 2 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
installed. Our recommended race sag with the new links is 2.75 to 3 inches
best performance. With our sag recommendations, the rear will not be lowered
the full 2 inches but will ride smoother on the small stuff and have more
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
mounting bolt and push it out the left side. *You may need to raise the
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

a race sag setting of 2.75 to 3.0 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"
stock, rounded on one end) to loosen the top jam nut from the right side,
the spring at the bottom and turn the spring and the preload nut at the
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.

can be slid up in the triple clamps until they almost contact the handle

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.
