Penske Racing Shocks 8900 Series - Manual (Page 2)

2
Your new Penske Racing Shock comes pre-adjusted at baseline settings. However, you must check
your rear sag before you race! This is very important for optimum performance.
Setting the Sag*
STEP 1
1) Without a rider on the bike,
have an assistant lift the
rear of the motorcycle until
the rear wheel is off the
ground slightly.
2) Using a tape measure,
measure the distance
between the axle center line
and a convenient location
on the rear subframe
(Figure 1).
3) Record this measurement as "A".
STEP 2
1) This step requires the rider
and two additional people.
2) One person should hold the
front of the motorcycle, straddling
the front tire.
3) Have the rider, wearing all of their gear, sit on the bike in a tuck position.
4) The third person should then measure the distance between the axle center line and a convenient
location on the rear subframe (same locations used in Step 1).
5) Record this measurement as "B".
STEP 3
1) Subtract "B" from "A". This number is your sag.
The amount of sag required varies from rider to rider and from track to track.
The sag should be between 7/8" and 1 1/6".
If the sag is greater than 1 1/6", preload the spring by turning the adjustable spring collar.
If the sag is less than 7/8", remove preload by turning the adjustable spring collar.
