1993-up Yamaha TTR-250.
( Lowers Rear
This link fits all the
TTR250 models including the ones that date back to 93 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 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 links be sure and grease both needle bearings
in the new link. After the stock link is removed, install the Kouba
Link in the reverse order, bearing end to the rear, 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 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 into 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 lowering is desired, race sag should
be set to 100 mm/3.90 inches.
4. We recommend sliding the
front fork tubes up (approx. ½ inch) until they almost touch the
bottom of the handle bars. 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.
