Bleeding the hydraulic clutch *
The clutch control needs to be bled as soon as the resistance in the clutch
lever starts to feel unresponsive. You will need to use a bleeding syringe (spe-
cial tool). Please note that Motorex 75 clutch fluid must be used for the 125
models and Motorex DOT. 5.1 brake fluid for the 250 models.
Both are available from your KTM dealer.
Turn the handlebar until the master cylinder is in a horizontal position, remove
the screws
[2]
, the cover
[3]
and the rubber boot
[4]
.
Fill the bleeder syringe
[8]
with a suitable fluid (see Technical Specifications
- Engine). Remove the bleeder screw from the slave cylinder
[9]
and mount
the bleeder syringe.
Changing the original position of the clutch lever
The adjusting screw
[1]
can be used for individual adjustment of the original
position of the clutch lever, thus allowing adjustment to an optimal position
for every hand size.
The clutch lever moves closer to the handlebar if the adjusting screw is tur-
ned in a counterclockwise direction. The clutch lever moves away from the
handlebar if the adjusting screw is turned in a clockwise direction.
Adjustment of the clutch lever position is only possible within certain limits.
Only turn the adjusting screw manually and never apply excessive force.

Checking the oil level of the hydraulic clutch125 SX
To check the oil level in the master cylinder of the clutch remove the cover.
For this purpose, remove screws
[2]
and cover
[3]
together with the rubber
boot
[4]
. The oil level in the horizontal-standing master cylinder should be
4 mm below the upper edge.
If necessary, add SAE 10 biodegradable hydraulic oil (Motorex clutch fluid
75), available from your authorized KTM shop.
KTM uses biodegradable, hydraulic mineral oil to actuate the hydraulic clutch
in 125/200 models. Do not mix this oil with any other hydraulic oil. Always
use original KTM hydraulic oil (available from your authorized KTM workshop)
to make sure your clutch operates smoothly. Never refill with brake fluid.
