TIP
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 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technicalskills.
