Chart notes

1. Items marked with an asterisk in the manual should be performed by a Yamaha dealer - they need special tools, data and technical skills.
2. Calendar items (coolant, brake fluid, fuel hose) sit in the Remarks column rather than in the interval columns.

From the manual

Service life of parts varies significantly with the environment the machine runs in (rain, dirt); inspect earlier if conditions are harsh.
Periodic inspection is essential to make full use of machine performance.
