1993-up Yamaha TTR-250.
( Lowers Rear
This link fits all the
TTR250 models including the ones that date back to 1993 in other countries.
1. Raise the motorcycle with
the center stand or milk crate, etc., so the rear wheel is slightly off
the ground. Remove both rubber plugs on the sides of the swing arm
and remove the 17 mm headed bolt inside the right side hole in the swing
arm. Push the remaining bolt/sleeve out the left side. You
may have to lift up on the rear wheel slightly to allow that sleeve to
slide out freely.
2. Next remove the 22 mm nut
and the washer from the mounting bolt on the left front side of the link,
and push the mounting bolt out the right side. The link should drop
out the bottom and you are ready to install the longer KoubaLink.
Before installing the new link be sure and grease both bearings. (Be careful
not to allow any of the needles to fall out of the race housing) If you
did not order the new bearings with the links you will have to push them
out of the stock links and reinstall them back into the new links.
3. Now that the stock link
is removed, install the KoubaLink in the reverse order, bearing end to
the rear, engraving to the outside with the grease fitting pointing down.
Install the front link mounting bolt with the washer from the right side.
Rotate the rear of the link up into the rear mounting house. Push
the rear mounting bolt/sleeve in from the left side through the link (you
will have to raise the rear wheel approx. 2 inches to line up the link
mounting hole and the holes in the swing arm) Install the 17mm headed
bolt back onto the end of the mounting sleeve on the right side, and torque
to approx. 20 lb-ft. Install the washer and the 22 mm nut on the
front mounting bolt and torque to approx. 30 lb-ft. Put the 2 rubber
plugs back in the swing arm holes. You may want to check the sag and if
the full 2 inches of rear lowering is desired, sag should be set at 100
4. We recommend sliding the
front fork tubes up (approx. ½ inch) until they almost touch the
bottom of the handlebars. The forks can be slide up ¼ inch
farther by shimming up the handle bar mounts up but any farther than that
could allow the front tire to contact the fender under full compression.
Sliding the fork tubes up less than 1 inch is preferred. If the rider would
like the bike to turn quicker we would recommend lessening the rear sag
which will subtract from the 2 inches of rear lowering.
