What bike can I ride without a full car licence?

[RileyFitz]

With just a Compulsory Basic Training (CBT) certificate, you can legally ride specific low-powered vehicles. At 16, you're restricted to a 50cc moped (max speed 28mph). At 17 or older, you can ride a 125cc motorcycle (max power 11kW, speed around 60mph). In both cases, you must display L-plates, cannot carry a pillion passenger, and cannot use motorways. The CBT certificate is valid for two years.

The core of the UK's provisional motorcycle entitlement is the CBT. It's not a test but a day of assessed training, confirming you can ride safely on the road. Upon completion, you receive a DL196 certificate, which grants you a provisional license for the corresponding vehicle categories.

The specific bikes you can ride are defined by their engine size, power output, and speed. For 16-year-olds, the only option is a moped classified as a category AM vehicle. This means an engine capacity no greater than 50cc and a maximum design speed not exceeding 28mph (45km/h).

For riders aged 17 and over, the scope expands to learner-legal 125cc motorcycles. The legal definition is precise: a motorcycle with an engine capacity up to 125cc, a power output not exceeding 11 kilowatts (about 14.7 brake horsepower), and a power-to-weight ratio not more than 0.1 kW per kg. Most standard 125cc models from major manufacturers like Honda, Yamaha, and KTM are designed to meet these limits, with typical top speeds around 60-65mph.

Rider Age After CBT Completion	Vehicle Type	Max Engine Size	Max Speed	Key Legal Conditions
16	Moped (Category AM)	50cc	28 mph (45 km/h)	L-plates (D-plates in Wales), no passenger, no motorways.
17 or older	Motorcycle (Category A1 Learner)	125cc	~60-65 mph (varies by model)	L-plates (D-plates in Wales), no passenger, no motorways. Power ≤ 11kW.

These entitlements come with non-negotiable restrictions. L-plates (or D-plates in Wales) must be clearly displayed on the front and rear of the vehicle. You are prohibited from carrying any pillion passenger. Riding on motorways is also illegal. Your CBT certificate is valid for two years from the date of issue. After it expires, you must either retake the CBT to continue riding as a learner or pass your full motorcycle theory and practical tests to gain an unrestricted license.

To progress, you must pass the motorcycle theory test and a two-part practical test (Module 1 off-road maneuvers and Module 2 on-road riding). Passing these tests on a 125cc bike grants you a full A1 license, which allows you to remove L-plates, carry passengers, and use motorways, but still restricts you to 125cc motorcycles. Further tests are required for larger bikes.

I got my CBT done last month after turning 17. My ride is a second-hand Honda CB125F. It’s perfect for my 10-mile commute to college. The rule is simple: big ‘L’ plates on the front and back, no giving mates a lift, and definitely no sneaking onto the motorway. The instructor drilled that into us. The certificate lasts two years, so my goal is to save up and pass my full test before it runs out. It’s freedom, but with very clear rules.

Let’s break down the practicalities. You’ve got your CBT certificate in hand—what does that actually let you do on the road? If you’re 16, you’re looking at 50cc mopeds, which are fine for short trips in town but will struggle on faster roads. For adults, the 125cc category opens up more possibilities. These bikes can handle most A-roads comfortably.

The real-world catch is the ‘learner’ status. Those fluorescent L-plates change how other drivers perceive you, and you need to be prepared for that. You’re also riding solo; no popping to the shops with a friend on the back. Plan your routes to avoid motorways entirely. Think of the CBT as a two-year license to learn and gain real experience, with the explicit goal of upgrading to a full license under its expiry countdown.

As a parent, understanding these rules is crucial for a young rider’s safety. The CBT system provides a controlled start. For a 16-year-old, the 50cc, 28mph limit creates a natural boundary. The mandatory L-plates alert other road users. The passenger and motorway bans are sensible safeguards during the learning phase. The two-year validity acts as a built-in reminder to either qualify properly or retrain. It’s not just about what they can ride, but the structured, restricted environment in which they’re allowed to do it. Always ensure they have the correct insurance and protective gear that meets safety standards.

From an instructor’s viewpoint, the CBT is a gateway, not a destination. The question isn’t just “what bike,” but “under what conditions.” The machine is the easy part: a compliant 125cc for adults or a 50cc moped for 16-year-olds. The critical details are the operating constraints. I emphasise to every trainee that the L-plates are a legal requirement, not a suggestion. The no-passenger rule is absolute. I map out local routes for them that explicitly avoid motorway junctions. My advice is always to book your theory test immediately after the CBT. Use the two-year window proactively. The goal is to convert that provisional entitlement into a full A1 license, shedding the restrictions and building a lifetime of safer riding on a proper qualification.
