This is the maintenance schedule and associated service intervals for the Yamaha XT225. It was produced for two decades exactly the same, with a 223-cc air-cooled carburettor-fed thumper in a dirt bike chassis.

Yamaha XT225 Maintenance Schedule
Below is the maintenance schedule for the Yamaha XT225.
The maintenance schedule has been simplified considerably compared to the one in the manual. Some simplifications made include:
- Removed the break-in schedule (it’s no longer relevant)
- Grouped together the most important items (oil changes, fluid changes, valve clearances)
- Put it together into one table, instead of separating out items related to emissions
- At the end of the maintenance schedule, keep following it in the pattern shown.
- Follow the earlier of time- or distance-based intervals. For example, oil should be changed every 4000 miles or 6 months.

About the Yamaha XT225
The Yamaha XT225 is a lightweight, easy-to-ride, tough-as-nails dual sport bike.
It’s equally good on road and trail, and is basically bomb-proof anywhere. It makes a great commuter bike, learner bike, or even something to teach people to ride on in basic motorcycle training courses.
The XT225 has low gearing down low to make it nimble enough to move through traffic, and high enough gearing to deal with the highway when needed.
The Yamaha XT225 is a true dual sport. It’s not a dirt bike with mirrors, nor is it a road bike with knobby tires. It has a big 21-inch front wheel and compliant long-travel suspension, but the gear is pretty basic — don’t expect the same degree of adjustability or suspension compliance you’ll get on an off-road race bike. The front fork is conventional (not inverted), for example.
Unusually for a dual sport, the XT225 is actually really good for short riders. It looks tall, but the suspension is soft and it’ll come down once you’re sitting on it. You can flat foot it even with a height of 5’6 or 165 cm.
The XT225 is carburettor-fed, which means you do need to use the choke in cold weather. But there’s just one carburettor (for the one piston), which is why you don’t see carburettor syncs in the maintenance schedule!
Speaking of which, the maintenance for the XT225 involves changing the oil every 3000 mi (5000 km), as well as a valve clearance check at every oil change. Since there’s only one cylinder and it’s easily accessible, it’s a fairly quick operation.
