CBT at 17: riding a 125cc on L plates

From 17, a CBT lets you ride a motorcycle or scooter up to 125cc. What that includes and what comes next.

· 2 min read

Seventeen is when motorcycling opens up. With a CBT certificate you can ride a motorcycle or scooter up to 125cc, which is enough for commuting, getting around London and the A roads.

What you can ride

  • A motorcycle or scooter up to 125cc.
  • Power output up to 11kW (about 14.6bhp).
  • A power-to-weight ratio of no more than 0.1kW per kg.

Most bikes sold as "125s" or "learner legal" meet these limits, but check before you buy.

The rules on L plates

  • Display L plates on the front and back of the bike (D plates in Wales).
  • No pillion passengers.
  • No motorways.

These apply for as long as you ride on your CBT.

How long can I ride on a CBT?

Two years. By then you need to pass your full test or take the CBT again. There's no limit on how many times you can retake a CBT, but most riders find the full licence worth it for the freedom it gives.

Your next step: A1

At 17 the full licence available to you is A1. It covers the same 125cc bikes but removes the L plates, and allows passengers and motorways. You'll need:

  1. A valid CBT.
  2. A motorcycle theory test pass.
  3. The module 1 and module 2 practical tests.

From 19 you can go for A2 instead, which covers more powerful bikes. See A1, A2 or A: which licence should you go for?
