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
should be followed.
