Inspecting The Front And Rear Suspensions; Front Suspension - APRILIA TUONO 1000 - 2006 Manual

INSPECTING THE FRONT
AND REAR SUSPENSIONS
CAUTION
The front fork oil change operation should
be entrusted to your Local aprilia
Dealer.
Carefully read page 79 (MAINTENANCE).
WARNING
Reduce the service intervals by half when
the vehicle is used in rainy or dusty
conditions, on rough roads or for racing.
NOTE
Reduce the service intervals by
half when the vehicle is used in rainy or
dusty conditions, on rough roads or for
racing.
Have the front fork oil changed after the
first 6,250 mi (10,000 km) and then every
12,500 mi (20,000 km).
Carry out the following checks after the first
625 mi (1,000 km) and every 6,250 mi
10,000 km) thereafter:
u Apply the front brake lever and push up and
down on the handlebar repeatedly, pushing
the fork up and down.
The fork must move smoothly and easily,
there must be no trace of oil on the fork
tubes.
u Check the torque of all the fasteners on the
front fork and inspect the entire front fork to
make sure that it is in good condition
without leaks or damage. Repeat for the
rear suspension and swingarm.
CAUTION
Do not ride your vehicle if either
suspension is damaged in any way,
contact your Local aprilia Dealer.

FRONT SUSPENSION

After the first 18,750 mi (30,000 km) and
then every 12,500 mi (20,000 km), check,
clean and lubricate the fork oil seals. If
necessary, have them replaced by an
aprilia dealer.
The front suspension is controlled by a
hydraulic fork, which is held to the steering
tube by two yokes.
Each fork leg is fitted with suitable
adjusters to modify suspension response.
An upper adjuster screw (1) controls
rebound damping, whereas a lower
adjuster screw (2) controls compression
damping. A top-mounted adjuster nut (3)
controls spring preload.
SETTING THE FRONT FORK
CAUTION
Do not force the adjusters (1-2) beyond
their limit stops in either direction, or
the threads may strip. Set both fork legs
t o t h e s a m e s p r i n g
compression and rebound damping
settings: a vehicle whose fork legs are
set to different settings will be unstable.
When spring preload is increased,
rebound damping should be increased
accordingly. Failure to do so may result
in the front end jerking unexpectedly
when riding.
For fork setting, see next page.
