Kalau sepeda motor sudah diservis, tinggal cek rem sebelum berangkat.

Here kalau introduces a condition, so the basic meaning is if.

In real usage, though, kalau can sometimes feel close to when if the speaker thinks the condition is likely or expected. So:

• Kalau sepeda motor sudah diservis...
  = If the motorcycle has already been serviced...

Depending on context, an English speaker might also understand it as something like once the motorcycle has been serviced or when it’s already been serviced, but if is the safest core meaning.

Sepeda motor is the standard full term for motorcycle / motorbike.

Word by word, it is:

• sepeda = bicycle
• motor = motor/engine

So sepeda motor literally means something like motorized bicycle, but in normal usage it simply means motorcycle.

In casual speech, many Indonesians do say motor, but sepeda motor is the clearer and more standard form, especially in neutral or careful language.

Sudah means already, and it marks that something has been completed.

So:

• sepeda motor sudah diservis
  = the motorcycle has already been serviced

Without sudah, the sentence would be less clearly about completion. It might sound more general or less focused on the fact that the servicing is finished.

So sudah is important here because the next step, checking the brakes, only makes sense after the servicing is done.

Diservis is a passive form. It means to be serviced or has been serviced.

Structure:

• di- = passive prefix
• servis = service

So:

• diservis = be serviced / serviced

The sentence is focusing on the motorcycle as the thing receiving the action, not on who did the servicing.

Compare:

• Mekanik menservis sepeda motor.
  = The mechanic services the motorcycle.
  (active: focus on the mechanic)

• Sepeda motor diservis.
  = The motorcycle is serviced.
  (passive: focus on the motorcycle)

In your sentence, the motorcycle is the topic, so the passive is very natural.

No. They look the same, but they are different things.

• di as a preposition means in, at, on and is written separately:
  
  • di rumah = at home
• di- as a prefix makes a passive verb and is written attached to the verb:
  
  • diservis = serviced / be serviced

So:

• di servis would normally be considered incorrect if you mean the passive verb
• diservis is correct

This is a very common point of confusion for learners.

That is one of its meanings, but here tinggal means something like:

• only need to
• just
• all that remains is to

So:

• tinggal cek rem
  = just check the brakes or
  = all that’s left is to check the brakes

This is a very common Indonesian use of tinggal.

Examples:

• Tinggal tunggu hasilnya.
  = Now we just need to wait for the result.
• Tinggal bayar saja.
  = You only need to pay now.

So in your sentence, after the motorcycle has been serviced, the remaining step is to check the brakes.

Cek is a very common everyday verb meaning check. It comes from English, but it is fully natural in modern Indonesian conversation.

A more formal or native-style alternative would be:

• memeriksa rem = to inspect/check the brakes

But cek rem sounds very natural, practical, and conversational, especially in instructions like this.

So the difference is roughly:

• cek = common, practical, colloquial
• memeriksa = more formal, more standard-written

Both are understandable, but cek fits the tone of this sentence well.

Rem means brake or brakes, depending on context.

In this sentence, English would most naturally say the brakes, because when checking a motorcycle, you usually mean the braking system in general, not just one brake part.

Indonesian nouns usually do not have a special plural ending like English does, so rem can cover either singular or plural depending on the situation.

So:

• cek rem
  = check the brake / check the brakes

In natural English here, check the brakes is the best translation.

Indonesian often omits the subject when it is obvious from context or not important.

So tinggal cek rem sebelum berangkat does not explicitly say:

• you
• we
• someone

But the meaning is still clear: it is a general instruction or practical statement, roughly:

• you just need to check the brakes before leaving
• all that remains is to check the brakes before departure

This kind of subject omission is very normal in Indonesian, especially in advice, instructions, and casual speech.

Both berangkat and pergi can relate to going somewhere, but they are not exactly the same.

• pergi = go
• berangkat = depart / set off / leave for a destination

Berangkat is especially common when talking about starting a trip, commute, or journey. That makes it very natural with a vehicle.

So:

• sebelum berangkat
  = before setting off / before leaving

In this sentence, berangkat sounds better because the speaker is talking about getting ready to use the motorcycle.

Yes. It can work either way, depending on context.

It could refer to one specific situation:

• If the motorcycle has already been serviced, just check the brakes before leaving.

But it can also sound like practical advice or a routine reminder:

• Whenever the motorcycle has been serviced, just make sure to check the brakes before setting off.

Indonesian often allows this kind of flexibility. Without extra time markers, the sentence can describe either a specific case or a general rule.
