GENERAL MAINTENANCE AND LUBRICATION CHART
NOTE:
From 18 months or 7,000 km (4,200 mi) or 210 hours, repeat the maintenance intervals starting from 6 months
or 3,000 km (1,800 mi) or 90 hours.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.
For TT-Rs not equipped with an odometer or an hour meter, follow the month maintenance intervals.
For TT-Rs equipped with an odometer or an hour meter, follow the km (mi) or hours maintenance intervals.
Hovewer, keep in mind that if the TT-R isn´t used for a long period of time, the month maintenance intervals

age.P.3-7 ~ 10
Gear shifter and clutchCheck that gears can be shifted correctly in order and that the
clutch operates smoothly.P.3-4
Throttle grip/housingCheck that the throttle grip operation and free play are correctly
adjusted. Lubricate the throttle grip and housing, if necessary.P.3-4 ~ 5

BRAKE SYSTEM AIR BLEEDING
(TT-R125LW/TT-R125LWE)
WARNING
Bleed the brake system if:
The system has been disassembled.
A brake hose has been loosened or
removed.
The brake fluid is very low.
The brake operation is faulty.
A dangerous loss of braking performance
may occur if the brake system is not prop-
erly bled.
1. Remove:
Brake master cylinder cap
Diaphragm
2. Bleed:
Brake fluid
Air bleeding steps:
a. Add proper brake fluid to the reservoir.
b. Install the diaphragm. Be careful not to
spill any fluid or allow the reservoir to
overflow.
c. Connect the clear plastic tube 2 tightly
to the caliper bleed screw 1.
d. Place the other end of the tube into a
container.
e. Slowly apply the brake lever several
times.
f. Pull in the lever. Hold the lever in posi-
tion.
g. Loosen the bleed screw and allow the
lever to travel towards its limit.
h. Tighten the bleed screw when the lever
limit has been reached; then release the
lever.

NOTE:
If bleeding is difficult, it may be necessary to
let the brake fluid system stabilize for a few
hours. Repeat the bleeding procedure when
the tiny bubbles in the system have disap-
peared.
j. Add brake fluid to the level line on the
reservoir.
WARNING
Check the operation of the brake after
bleeding the brake system.
