2. Items with “*” mark indicate our recommendation to have it done by Genuine dealer.
NOTE 1:
For 4T engine, the engine oil shall be changed completely after run-in period 300km or one month later.
This can make sure the engine runs smoothly.
NOTE 2:
The exchange of brake fluid
1. After disassembling of brake main cylinder or caliper, do change the new fluid.
10

2. Check the fluid level often, Refill if necessary.
3. Change the oil seal of main cylinder and caliper every two years.
4. Change the brake fluid hose every four years.
