Honda CRF150R/RB Lowers the rear 1.625"
"R" model and 1.750" on the "RB".

1) Raise the motorcycle with a bike
stand, milk crate, etc., so the rear wheel is just slightly off the ground.
two 17 mm nuts that hold the “H” link to the rocker and the engine cradle
and push the bolts out the left side/front mounting
2) The new links come with only the bearings and seals, so install
the center sleeve
from your old OEM link into
end of the KoubaLink before you install it on the bike. Install the
new Koubalink on the bike (rear mounting bolt first,
grease fitting facing back and down) by pushing the mounting bolts in from
the left side. You will have to raise the swingarm
to align the front mounting holes.
3) After installing the KoubaLinks, be sure the 90 degree grease
fitting is facing down. *Left link engraving will be upside
down and backwards, right side will be readable left to right. Install
the washers/nuts, torque to 32 lbs-ft.
4) For the best performance, set the race sag (amount of vertical
movement of the rear axle FROM no weight to bike weight
plus rider weight) at 2.5" to 3.0" (depending on rider preferences) with
rider in full riding gear, standing on the pegs.) The
easiest way we have found to adjust the rear spring preload is to use a
long punch to loosen the top jam nut from the right
side and grasp the spring at the bottom and turn the spring and the preload
nut a turn freely. 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. We recommend sliding the fork tubes up in the triple clamps
until they almost touch the under side of the
handlebars. Sliding the fork tubes up until they barely clear the
bottom of the stock bars raises them 5/8th inches on the "R"
model and 1.4 inches on the "RB" model from the index line on the fork
tubes. *Do not over torque the triple clamp pinch
bolts after sliding the tubes up. (14 lbs-ft. lower, 17 lbs-ft. upper.)
5) You should now be ready to give it a try, remember, sliding the
fork tubes up farther and/or lessening the rear sag
quickens the steering and visa versa.
Disclaimer: Lowering the rear more than the front can change the
geometry and could affect the handling, so be careful
