Oil quantity: (505 ± 2.5) cu cm (30.81 ± 015) in.
Oil level: 122 ± 2 mm (4.80 ±0.08 in); (from edge of
sleeve)
NOTE To correctly measure the oil level the sleeve must be
perfectly vertical. The oil level must be the same in both
legs.
The standard adjustment of the fork meets most conditions
of high and low speed riding, whether the vehicle is
travelling with a full load or not.
It is however possible to customise the adjustment,
depending on how the vehicle is used.
WARNING
When proceeding with the adjustment, always
start from the stiffest setting (adjusters 1 and
2 turned completely clockwise). As a reference
for adjusting
damping, use the marks on the adjusters (1-2).
Gradually turn the adjusters (1-2) by 1/8 of a
turn each time.
