Everything You Need to Know About Irish Motorcycle Licences and Engine‑Capacity (CC)
If you’ve ever walked past a biker on a sleek 600 cc machine and wondered whether you could legally ride one, you’re not alone. In Ireland the rules that tie engine‑capacity (CC) to the type of licence you need are clear, but they can feel a little tangled the first time you look at them. This guide walks you through every step of the process, from the age you can start learning to the exact CC limits for each licence category, plus the paperwork, fees and common pitfalls to avoid.
1. Why Engine Capacity Matters
Motorcycle engines are measured in cubic centimetres (cc). The higher the cc, the more air‑fuel mixture the engine can burn, which translates into more power and higher top speeds. Because larger bikes can be more difficult to control, Irish law groups them into three licence categories, each with its own CC ceiling and minimum age.
Bottom line: You can only ride a motorcycle whose CC is equal to or lower than the limit attached to the licence you hold.
2. The Three Irish Motorcycle Licence Categories
| Licence Category | Minimum Age | Maximum Engine Capacity (CC) | Typical Bikes You Can Ride | Required Tests | Restrictions (if any) |
|---|---|---|---|---|---|
| A1 | 16 (with a provisional) / 17 (full) | 125 cc (max 11 kW) | Honda CB125R, Yamaha MT‑125, KTM 125 Duke | Theory + 2‑hour practical (maneuver, off‑road, road) | None once full licence is granted |
| A2 | 18 | 35 kW (≈ 47 bhp) – no bike > 0.2 kW per cc (i.e., 175 cc) | Kawasaki Ninja 400, Honda CBR500R, BMW G 310 R | Theory + 2‑hour practical (same as A1) | Must not exceed 0.2 kW/cc ratio |
| A (Full) | 24 (or 20 with A2 for 2 years) | No limit (unrestricted) | Triumph Street Triple, Ducati Monster 1200, Harley‑Davidson 1200 | Theory + 2‑hour practical (including high‑speed & emergency stop) | No CC limit; must have held A2 for 2 years if under 24 |
How the CC Limits Translate in Practice
- A1 (125 cc) – Ideal for city commuting, beginners, and riders who want a lightweight bike that’s easy to handle.
- A2 (up to 35 kW) – Gives you enough power for highway riding while still capping the bike’s performance to keep it manageable.
- Full A (unrestricted) – Opens the door to any motorcycle, from nimble sport‑bikes to heavyweight cruisers.
3. Step‑by‑Step Road‑To‑Licence Journey
Below is the checklist you can tick off as you progress from a hopeful rider to a fully‑licensed motorcyclist.
- Check Eligibility – Confirm you meet the age requirement for the category you aim for.
- Pass the Driver Theory Test – Book online via the RSA (Road Safety Authority) portal.
- Obtain a Provisional Licence – You’ll need a valid National Driver Licence (NDL) and a recent passport‑style photo.
- Complete a Recognised Training Course – The RSA accredits several schools (e.g., Motorbike Safety & Training, Bikesteel).
- Pass the Practical Test – Consists of off‑road manoeuvres (U‑turn, figure‑8, emergency stop) and a road ride.
- Apply for the Full Licence – Once you’ve passed, submit the test certificate to the National Driver Licence Service (NDLS).
Quick Reference Table: Fees & Timing
| Item | Approx. Cost (€) | Typical Processing Time |
|---|---|---|
| Theory Test (online) | 15 – 20 | Immediate confirmation |
| Provisional Licence (incl. photo) | 30 | 1–2 weeks |
| Training Course (A1/A2) | 400 – 600 | 2–3 days of intensive training |
| Practical Test (A1/A2) | 70 – 80 | Results on the day |
| Full Licence issue (after passing) | 30 – 40 | 2–3 weeks (post‑test) |
| Full A upgrade (after 2‑year A2) | 40 | Same as above |
Tip: Many training schools bundle the theory fee, training, and practical test into a single package—often a better value than paying each item separately.
4. Common Misconceptions About “CC”
| Myth | Reality |
|---|---|
| “If I have a full A licence, I can ride any bike, even a 200 cc scooter.” | True – a full A licence removes all CC limits. The myth is not about the ability but about the need for a different licence class for mopeds (Category AM). |
| “A 250 cc bike automatically falls under A2.” | No. The A2 limit is power‑based (35 kW), not simply CC. Some 250 cc bikes produce more than 35 kW and are therefore restricted to full A. |
| “You can ride a 600 cc bike on an A2 licence if you keep the revs low.” | Incorrect. The maximum power output of the bike determines the licence, regardless of how you ride it. |
| “A provisional licence lets you ride on public roads.” | With a provisional and a learner plate (L‑plates) you may ride, but only after you’ve passed the theory test and are accompanied by a qualified rider. |
5. Choosing the Right Bike for Your Licence
When you’re ready to buy (or rent) a motorcycle, use this simple checklist to ensure the bike fits your licence class:
- Check the Bike’s Power Output – Look for the listed kW or bhp in the specifications.
- Calculate the kW/cc Ratio – For A2, the ratio must be ≤ 0.2 kW per cc.
- Confirm the CC Ceiling – Ensure the engine size does not exceed the CC limit for A1 or A2.
- Consider Insurance Costs – Younger riders on lower‑capacity bikes often enjoy cheaper premiums.
- Test Ride (If Possible) – Even within the same CC range, handling can differ dramatically (e.g., a naked bike vs. a sport bike).
Sample Bike Recommendations by Category
| Licence | Recommended Models (2024) | Approx. CC | Approx. Power (kW) |
|---|---|---|---|
| A1 | KTM 125 Duke, Honda CB125R, Yamaha MT‑125 | 124‑125 | 9‑11 |
| A2 | Kawasaki Ninja 400, Honda CBR500R, Royal Enfield Himalayan 411 | 399‑500 | 30‑35 |
| Full A | Ducati Monster 1200, Triumph Street Triple 765, Harley‑Davidson Street 750 | 600‑1200+ | 50‑110+ |
6. Frequently Asked Questions (FAQ)
Q1: Can I ride a 125 cc scooter with an A2 licence?
A: Yes. An A2 licence permits you to ride any motorcycle up to 35 kW, regardless of its CC. Since most 125 cc scooters produce far less than 35 kW, you’re good to go.
Q2: Do I need a separate licence for an electric motorcycle?
A: No. Electric bikes are classified by maximum power output (kW) rather than CC. The same A‑category limits (A1: ≤ 11 kW, A2: ≤ 35 kW, Full A: unrestricted) apply.
Q3: What happens if my bike’s power is slightly over 35 kW but its CC is under 125?
A: The licence is based on power, not CC. If the bike exceeds 35 kW, you’ll need a full A licence regardless of its displacement.
Q4: I’m 22 and have an A2 licence. When can I upgrade to a full A licence?
A: You can upgrade after two years of holding a full A2 licence (i.e., at age 24) or after one year if you complete the Compulsory Basic Training (CBT) conversion course that proves you can handle higher‑power machines.
Q5: Are there any geographical restrictions on using a motorcycle licence?
A: Your Irish licence is valid throughout the EU. However, if you ride in the UK, you must carry your full licence and may be asked for a passport‑style photo ID. Some insurers require you to notify them if you ride abroad for extended periods.
Q6: Can I ride a 600 cc bike on a provisional licence?
A: No. A provisional licence only allows you to ride after passing the theory test and with L‑plates, and you must be accompanied by a rider with a full licence for the same category. For a 600 cc bike you need a full A licence.
Q7: How do I find a recognised training school near me?
A: Visit the RSA’s website and use the “Find a Training Provider” tool. Enter your county or postcode, and you’ll get a list of approved schools with contact details and course fees.
7. Practical Tips to Keep Your Riding Journey Smooth
| Tip | Why It Helps |
|---|---|
| Start with a low‑CC bike even after getting an A2 licence. | It builds confidence and lets you master basic manoeuvres without being overwhelmed by power. |
| Schedule your theory exam early – spots fill up quickly, especially in summer. | Guarantees you can start the practical training when you want. |
| Keep your licence documents with you at all times, especially when riding a high‑capacity bike. | Police may request proof of unrestricted licence for larger motorcycles. |
| Maintain your bike regularly – check tyre pressure, oil level, and brake fluid before each ride. | Reduces the risk of mechanical failure, which is more critical at higher speeds. |
| Consider a “progressive upgrade” insurance policy. | Some insurers lower premiums if you agree to upgrade licence categories only after a set period of safe riding. |
8. Wrapping Up: Your Road Map to Riding Freedom
You now have a clear picture of how engine capacity (CC) ties into the Irish motorbike licensing system, what steps you must take, and which bikes fit each licence class. Remember:
- Age + power = licence – the combination determines what you can legally ride.
- Training matters – a reputable RSA‑approved school not only prepares you for the test but also teaches safe riding habits that will protect you for years to come.
- Stay informed – legislation can evolve (e.g., new electric‑motorbike categories), so keep an eye on RSA updates.
The open road is waiting, and with the right licence in your pocket, you’ll be able to choose the perfect machine—whether it’s a nimble 125 cc commuter, a versatile 400 cc roadster, or an unrestricted superbike that roars across the Irish countryside.
Happy riding, and enjoy the freedom that comes with mastering your motorcycle licence!
