Warning
Th is vehicle uses a
tubeless tire
system in
which
a
rim
seal
band
O
is
used
i
nstead
of
the
conventional
tube.
The
advantages
of
the
tubeless
system
l
ie
in
the absence of
dan-
ger
from
a fau
lty
tube.
This
greatly
reduces
the risk of a sudden
loss
in
pressure.
The masses
and
moment
s of inertia of
t
hese wheels are
smaller
t
han
in
conventio11al
spoke
wheels with a
t
ube.
This
resu lts
in bet-
ter
handling and r iding comfort.
The
rigid rim design
results
in a spoke
wheel that
is almost
ent
irely maintenance-free.
KTM
recommends
that
the rim
seal
band be changed after 5
years
at the
latest,
regard less of
the
actual stat
e
of
wear.
Danger of
accidents
Incorrectly tensioned spokes
impair
the
handling characteristic
and result in
sec-
ondary damage.
The spokes
break
due to being overloaded
if
they
are
too t
ightly
tensioned.
If the
tension
in
the spokes
is
too low, then lateral and rad ial run-out wi
ll
form in the w heel.
Other
spokes will become looser as a
result.
-
Check spoke tension regularly, and
in particular
on a new
vehicle.
-
Strike
each spoke
briefly using
a screwdriver
blade.
•
Info
I
The
frequency
of
t
he sound depends on the spoke
length
and spoke diameter.
If
spokes
of the
same length
and d iameter vibrate
with
a different tone, t
his is
an indication that
the
spoke
tensions
differ.
I
You should hear
a high note.
•
If
the
spoke
tension
differs:
-
Correct
t
he
spoke
tension.
