Registering a 50cc moped in Western Australia costs roughly a third of what it costs to register a 125cc scooter — and the reason has nothing to do with the bike's value, its weight, or how far you ride it. It comes down to a single line in WA's compulsory insurance schedule: the 75cc threshold.
This guide breaks down every component of a WA scooter registration bill, what the 2026/27 fees actually are, and what you'll pay on top when you buy.
What Does It Cost to Register a Scooter in WA?
Here is a 12-month registration for two typical commuter bikes, built from Transport WA's published 2026/27 rates:
| Component | 50cc moped | 125cc scooter |
|---|---|---|
| Vehicle licence fee (motorcycle ≤250cc) | $72.72 | $72.72 |
| Motor injury insurance premium | $70.20 (Class 7(a)) | $342.95 (Class 4) |
| MII including 10% GST and 10% insurance duty | ~$84.94 | ~$414.97 |
| Recording fee (12 months) | $9.70 | $9.70 |
| Approximate annual total | ~$167 | ~$497 |
That is a difference of around $330 a year, every year, between two bikes that might be parked next to each other.
Your renewal notice is the authority on the exact figure — it will show the precise amounts for your bike, and concessions can change the total.
The 75cc Rule: Why a Moped Is So Much Cheaper to Register
Every registered vehicle in WA carries compulsory Motor Injury Insurance (MII), administered by the Insurance Commission of WA and collected together with your vehicle licence. It covers injury or death caused to other people. It does not cover damage to your own bike, or to anyone's property.
MII is priced by vehicle class, and motorcycles sit in two very different ones:
| MII class | Covers | 2026/27 premium |
|---|---|---|
| Class 7(a) | Motorcycles not exceeding 75cc, including hire use | $70.20 |
| Class 4 | Motorcycle (other than those in Classes 5(b) and 7(a)) | $342.95 |
A 50cc moped falls under Class 7(a). A 125cc scooter — or anything else above 75cc — falls under Class 4, at nearly five times the premium. GST at 10% and insurance duty at 10% apply on top of both.
There is no sliding scale and no middle band. A 75cc scooter pays $70.20. An 80cc scooter pays $342.95.
This is worth knowing before you buy rather than after, because it stacks on top of the licensing difference. A 50cc moped can be ridden on a car licence in WA, while anything above 50cc needs a motorcycle licence — our WA scooter and motorcycle licence guide covers that side of it.

The Three Parts of a WA Registration Bill
1. Vehicle Licence Fee
Most light vehicles in WA are charged by weight, at $29.76 per 100kg. Motorcycles are not. They pay a flat annual fee instead:
| Motorcycle category | 12-month fee |
|---|---|
| Not exceeding 250cc | $72.72 |
| Power-to-weight ratio not exceeding 150 kW/t | $102.48 |
So a 50cc moped and a 250cc scooter pay exactly the same licence fee. The licence fee is not where the moped saving comes from — the insurance is.
2. Motor Injury Insurance
Covered above: $70.20 for 75cc and under, $342.95 above that, plus GST and insurance duty on each.
3. Recording Fee
A flat administration charge applied to every renewal:
| Term | Recording fee |
|---|---|
| 3, 6 or 12 months | $9.70 |
| 12 months by direct debit | $9.50 |
| 1 month | $1.75 |
Vehicle Licence Duty (Stamp Duty) When You Buy
Separate from registration, and paid once when the bike is first licensed in your name. WA calls it vehicle licence duty; most people call it stamp duty.
For vehicles of 4.5 tonnes or less, the rates are:
| Dutiable value | Duty rate |
|---|---|
| Up to $25,000 | 2.75% of dutiable value |
| $25,000 – $50,000 | Graduated, 2.75% rising to 6.5% |
| Over $50,000 | 6.5% of dutiable value |
Nearly every scooter and commuter motorcycle sits in the first bracket:
| Purchase price | Duty payable |
|---|---|
| $3,000 | $82.50 |
| $6,000 | $165.00 |
| $9,000 | $247.50 |
| $12,000 | $330.00 |
For a new bike, dutiable value is based on the manufacturer's recommended retail price in WA — including factory options such as engine size or transmission, but excluding dealer delivery charges, insurance and aftermarket accessories. For a used bike bought privately, you declare the value on the transfer form, assessed against open-market value.
Concessions exist for pensioners and veterans holding qualifying cards, for transfers between spouses and de facto partners, and for several other categories.
3, 6 or 12 Months?
WA does not force you into annual registration. A bike can be licensed for 3, 6 or 12 months, which helps if you are not certain you will keep it or you would rather spread the cost.
The trade-off is small but real. A short-term fee of $5.44 applies to the insurance component for any period under 12 months, and the $9.70 recording fee is charged each time rather than once a year. Registering quarterly means four recording fees and four short-term fees across the year — roughly $60 more than paying for 12 months up front.
If you are buying a new bike from us, the registration term is set at the time of purchase, so it is worth deciding before the paperwork goes in rather than after.
How to Register a Scooter in WA for the First Time
If the bike is not already licensed — an unregistered private sale, an interstate bike, or an import — you will need to license it yourself:
- Get it inspected. Book an Authorised Inspection Station (AIS) and obtain a Certificate of Inspection.
- Complete Form VL17 (Application to License a Vehicle).
- Provide identification — one primary and one secondary form. If this is your first WA vehicle licence and you do not hold a WA driver's licence, you will also need Form VL186.
- Prove ownership — receipts, a bill of sale, or current licence papers.
- Lodge it at a DTMI service centre or regional agent, and pay the licence fee, MII and duty.
A weighbridge certificate is also required if the bike's tare weight cannot otherwise be verified, though that is rarely an issue for a mainstream scooter with documented specifications.
Buying from a dealer avoids all of this — the bike arrives licensed, with the paperwork handled as part of the sale.
Buying Privately: Transferring the Licence
If the scooter is already registered, you are transferring an existing licence rather than creating a new one.
- The transfer must be lodged within 14 days of purchase. Miss it and a penalty applies.
- Transport WA then issues an invoice covering the transfer fee, vehicle licence duty and any concession adjustments. Allow up to 21 days for it to arrive.
- That invoice must be paid within 28 days.
The transfer fee itself is not published in advance — it is calculated and issued on the invoice alongside the duty. Budget for the duty, at 2.75% of value for anything under $25,000, as the substantial part.
Before handing over money on a private sale, run a PPSR check and inspect the bike properly. Our guide to buying a used scooter in Perth covers what to look for.
Do You Need to Register an Electric Scooter?
It depends entirely on which kind you mean.
Personal e-scooters (eRideables) — the stand-on kind, capped at 25 km/h — need no registration, no licence and no MII. They are a separate legal category with their own rules, covered in our WA e-scooter laws guide.
Electric mopeds and electric motorcycles are registered road vehicles, treated like any other bike: licence fee, MII, duty, plates.
One wrinkle worth raising with Transport WA directly before you buy: MII Class 7(a) is defined by engine capacity — "not exceeding 75cc" — and an electric moped has no cc rating at all. Which class an electric moped is assigned to is not something the published schedule settles cleanly, and it makes a difference of several hundred dollars a year. Confirm it rather than assuming an electric moped registers as cheaply as a petrol one.
What Registration Doesn't Cover
The MII bundled into your registration covers injury to other people. It does not cover:
- Damage to your own scooter
- Damage to someone else's vehicle or property
- Theft
If a driver reverses into your parked scooter, MII does nothing at all. Comprehensive or third-party property insurance is a separate purchase. On a low-value bike, plenty of riders reasonably decide to skip it — but that should be a decision rather than an assumption.
