It is possible to change the oil by following the steps as shown. Changing the oil frequently(20-30hrs) will
allow you to keep the ERA sliding components in excellent condition, and increase wiper seal longevity. This
operation may be performed with the fork installed on the bike.

Stop the foot stud rotation with the 4mm
Allen wrench and use the 19mm to
unscrew the outer nut. Repeat the
operation each side.
Attention: Rotating the 4mm instead of
the 19mm may result in damage to the
foot nut. If foot stud does not break free
under normal pressure apply heat. Do
not let the central stem fall back into the
lower to avoid introducing dirt and
impurities. Clean both stems ends with a
cloth and put the removed nuts in a safe
place.
•Box End Wrench
19mm
• Allen key 4mm
•Clean bowl for storage
Now replace the bike to the normal
position on the stand. Place an oil
recovery tank under the fork. With
the rubber hammer gently hit the
lower arch to make it run down about
10 cm. Do not fully extract the lowers.
Let all the oil run out from them, for
about 10 minutes.
• Rubber hammer
Once again rotate the bike upside down
or place on the floor so you will be able
to work on the bottom of the lower.
Keep the lowers drawn down about 10
cm. Using a graduated syringe insert
the correct quantity of oil inside the
lowers.
• Hydraulic side: 25cc
• Air side: 10cc
Quantities are slightly lower than those
indicated in the rest of this guide due
to residues that will remain inside the
lowers.
• Syringe 30cc min.
