Yamaha YZF-R125 Service Manual: Periodic maintenance and lubrication chart
NOTE:
- The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a mileage-based maintenance, is performed instead.
- From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
- Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical skills.
NOTE:
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake service
- Regularly check and, if necessary, correct the brake fluid level.
- Every two years change the brake fluid.
- Replace the brake hoses every four years and if cracked or damaged.
