Adjustments 149
Rear Suspension Adjustments
Ask the other helper to measure the loaded
with rider dimension.
Example:
4. Calculate the race sag dimension.
To do this, subtract the loaded with rider
dimension (step 3) from the unloaded
dimension (step 2).
Standard Race Sag: 4.1 in (105 mm)
Adjust spring pre-load as necessary to obtain
the desired handling results.
Decreasing the race sag dimension (example:
3.7 in, 95 mm) improves turning ability for
tight terrain at the cost of slightly reduced
straight line stability.
Increasing the race sag dimension (example:
4.5 in, 115 mm) may improve stability on
faster terrain with less turns, but will reduce
turning performance slightly and may upset the
balance between the front and rear suspension,
producing a harsher ride. This will happen if
the adjustment shifts the effective wheel travel
toward the more progressive end of its range.
Unloaded = 24.6 in (625 mm)
– Loaded = 20.7 in (525 mm)
Race Sag = 3.9 in (100 mm)
