Yes. Everyone must take a motorcycle theory test and CBT before they can take the motorcycle practical test. The only exception is for someone who has already passed a Motorcycle or Moped test, and wants to upgrade to a higher power machine. 

The Theory Test consists of 50 questions on the highway code and you will need to get at least 43 right out of the 50, coupled with the Theory Test is the Hazard Perception.

The actual DSA Hazard Perception Test has 14 different moving scenes shown from moving video clips filmed from a car. The scenes will have one or two hazards to identify. The 14 scenes will be taken from a bank of 200.
