- Lift the motorcycle so to disengage the bra-
king disc (left wheel side) from caliper.
To re-assemble the wheel operate vice-versa.
After re-assembling check clearance between
pad and disc (See chapter "Checking pad
wearing .. ).

frame: and remove silencer from exhaust
tube after undoing the screw securing its
fixing clamp.

To re-fit the wheel operate vlceversa.
Remember to fit caliper on the rear swi nging
arm (left) and to check clearance between pad
and braking disc. (See proper chapter in section

ADJUSTING THE SPOKES
Check that all spokes are tightened and the
wheel is correctly trued by proceeding as fol-
lows :
• spin the wheel and check its truing if ne-
cessary act on right or left spokes until the
wheel turns properly. This checking has to be
carried out after the fi rst 500 km (300 miles)
and later on, every 1500 km (900 miles) or so.
WHEEL BALANCE
To improve stability and decrease vibrations at
high speeds the wheels have to be kept ba-
lanced.
Operations are as follows:
• after removing the wheel and checking spoke
tightening and wheel truing suspend it on a fork ;
• spin the wheel lightly several times and see
if it stops always in various positions, thus Indi-
cating a correct balance;
• if one point of the wheel always stops at the
baHam, put a balance weight on a spoke oppo-
site that pOint.
• repeat this operation until the wheel is cor-
rectly balanced then fix the balance weights to
the spokes by means of pliers.
Balance weights are available from our dealers
in sizes of 15, 20, 30 grams.
Normally, an imbalance 01 less than 15 grams
does not affect the motorcycle stability.
TYnES
The tyre condition is of main importance as sta-
bility of motorcycle. riding comfort and even
rider safety are depending on this factor.
It
is therefore quite advisable not to use tyres
with tread lower than 1.5
-7-
2 mm respectively
front and rear tyre.
A wrong tyre pressure can also affect stability
of motorcycle and shorten type life .
Correct pressure is:
- front wheel : solo or with pillion kp/ cm': 2
- rear wheel : solo kp/ cm': 2.3
- with pillion: kp/ cm': 2.5.
These data are for normal riding (touring). In
case of constant high speed or motorway riding
increase lyre pressure 0,2 kg / cm 2 •
