! WARNING !
Excessive tensioning of the chain
will put additional load on the
components of the secondary drive
chain (chain, bearings and rear
wheel). Aside from resulting
premature wear, chain may rupture
or transmission countershaft may
break.
On the other hand, too much slack
in the chain can result in chain
jumping off the chain wheels. If this
happens, chain could also block rear
wheel or damage the engine.
In either case, operator is likely to
loose control of the motorcycle.
Drive chain maintenance
A good maintenance is very important
for long chain life. Chains without o-
rings should be cleaned in fireproof
solvent regularly and afterwards treated
with hot grease or chain spray. On the
other hand, o-ring chains are very
simple to clean. The best way is to use
lots of water but never use brushes or
cleaning liquids. After letting the chain
dry completely, use a chain spray to
lubricate it.
Also check sprockets and chain guides
for wear and replace if necessary.
! WARNING !
No lubrication should be allowed to
reach rear tyre or rear brake disc,
otherwise road adherence and rear
wheel braking effects will be
strongly reduced and the
motorcycle can easily get out of
control.
! CAUTION !
When mounting chain master link
clip, the closed side of the master
link must point in the running
direction.
BRAKES
Brake pads
Brake pads used on front and rear
brake provide an optimal combination
of power, brake performance and
lifecycle.
Brake discs
Due to wear, the thickness of brake
discs in the area of the contact face (1)
of the brake pads decreases. At their
thinnest point (A), the brake discs must
not be more than 0.50mm thinner than
the pads nominal thickness. Measure
the nominal thickness in a location (B)
outside the contact face and check for
wear in several locations.
! WARNING !
For your own safety, have the
brake discs replaced immediately
as soon as they reach wear limit (3
mm thickness).
Have any repairs on brake system
performed by an AJP authorized
dealer.
Brake fluid reservoirs
Brake fluid reservoirs have been
designed in such a way that even if the
brake pads are worn it is not necessary
to refill brake fluid. If brake fluid level
drops below the minimum level, either
the brake system has a leak or the
brake pads are completely worn.
