Xe máy này cần bảo dưỡng.

Xe máy means motorbike, motorcycle, or very often scooter in everyday Vietnamese.

A quick breakdown:

• xe = vehicle
• máy = machine / motor

Together, xe máy refers to a motor-powered two-wheeled vehicle. In real life, it usually means the kind of motorbike people commonly ride in Vietnam.

In Vietnamese, demonstratives like này often come after the noun.

So:

• xe máy này = this motorbike
• literally: motorbike this

This is normal Vietnamese word order. A useful pattern is:

• noun + này = this ...
• noun + đó / kia = that ...

Examples:

• nhà này = this house
• người này = this person

Cần means need or to need.

In Xe máy này cần bảo dưỡng, it shows that the motorbike needs something to be done.

A very common pattern is:

• Subject + cần + verb

Examples:

• Tôi cần nghỉ. = I need to rest.
• Xe này cần sửa. = This vehicle needs repairing.

So here:

• cần bảo dưỡng = needs maintenance / needs servicing

Bảo dưỡng means to maintain, to service, or maintenance/servicing.

It usually refers to routine care to keep something working well, such as:

• changing oil
• checking parts
• regular servicing

This is different from:

• sửa = fix, repair
• sửa chữa = repair

So the difference is roughly:

• bảo dưỡng = maintenance, preventive care
• sửa / sửa chữa = repair after something is wrong or broken

Because of that, Xe máy này cần bảo dưỡng usually suggests:

• the bike needs servicing rather than
• the bike is broken and needs repair

Vietnamese often does not use articles like English a or the.

So:

• xe máy can mean a motorbike, the motorbike, or just motorbike, depending on context.

Also, there is no need for is here because cần is already the main verb:

• Xe máy này = this motorbike
• cần = needs
• bảo dưỡng = maintenance / servicing

So the sentence is already complete without a separate word meaning is.

It can naturally be understood as either one, depending on how you translate it into English.

Vietnamese often uses:

• cần + verb

even when English might prefer:

• needs to be + past participle

So:

• Xe máy này cần bảo dưỡng can mean
• This motorbike needs maintenance or
• This motorbike needs to be serviced

Both are good English translations.

Vietnamese often leaves this kind of meaning implicit.

In English, we often say:

• The bike needs to be serviced

In Vietnamese, it is very common to simply say:

• Xe máy này cần bảo dưỡng

Even though bảo dưỡng literally looks like an active verb, the whole sentence naturally means that the bike needs servicing.

If you want to make the passive idea more explicit, you can say:

• Xe máy này cần được bảo dưỡng.

Here, được helps mark that something is done to the motorbike.

However, in everyday speech, leaving out được is very common and natural.

Yes. That is completely natural.

Chiếc is a classifier often used for vehicles and some other objects. So:

• Xe máy này cần bảo dưỡng.
• Chiếc xe máy này cần bảo dưỡng.

Both are correct.

The version with chiếc can sound a bit more complete or slightly more careful, but in everyday speech people often omit classifiers when the meaning is already clear.

It functions very much like a verb here: to maintain / to service.

Vietnamese words are flexible, and many can behave like verbs or nouns depending on context.

In this sentence:

• cần bảo dưỡng = need servicing / need to be maintained

In another context, bảo dưỡng can also refer to the idea of maintenance more generally.

So the most helpful way to understand it here is:

• bảo dưỡng = to service / to maintain

To make it negative, put không before cần:

• Xe máy này không cần bảo dưỡng.
• This motorbike does not need servicing.

To make it a yes-no question, use có ... không around the verb:

• Xe máy này có cần bảo dưỡng không?
• Does this motorbike need servicing?

This pattern is very common:

• Subject + có + verb + không?

A rough pronunciation guide is:

• Xe máy này cần bảo dưỡng
• approximately: seh mai nai gun bao yuhng

A few helpful notes:

• xe sounds close to seh
• máy has a rising tone
• này has a falling tone
• cần has a low tone
• bảo has a dipping/rising kind of contour
• dưỡng has a ng-sound at the end and a complex vowel

If you are learning pronunciation, it is especially worth listening carefully to:

• xe
• máy
• dưỡng

because those may not match English spelling expectations very well.
