The Moped That Will Not Stay Legal
A 17-year-old buys a second-hand AM moped. The previous owner fitted an aftermarket exhaust and a variator kit and tells him it now reaches 62 km/h on the flat. The moped's registration documents still describe it as a 45 km/h class AM vehicle. The tyres are the original size but the rear one is worn close to the wear indicator. The front brake works but the rear brake cable is slack, and the horn is broken. The young rider plans to ride it to a friend's house 8 km away on a Saturday afternoon, mostly on 50 km/h roads. He thinks the modifications are fine because the moped still looks standard and he has not been stopped before.
1. Identify the technical and legal problems with this moped and explain why each matters for AM use.

The variator kit and exhaust change the vehicle's speed capability beyond the AM class limit, so it no longer matches its registration documents. That is a legal problem: the vehicle is no longer the class AM machine described on its papers, and riding it can amount to riding an uninsured or incorrectly registered vehicle, with penalties and insurance consequences. The worn rear tyre reduces grip, especially in the wet and under braking, and a tyre at the wear indicator should be replaced. The slack rear brake cable means the rear brake may not operate effectively, cutting the braking performance the rider relies on. A broken horn removes a required safety device. Each defect is independently a reason not to ride; together they make the moped unsafe and non-compliant.
2. What should the rider do before using the moped, and what are the risks of riding it as it is?
Read the worked answer
He should not ride it until it is restored to a compliant, roadworthy condition: refit a standard exhaust and variator so it matches its documents, replace the worn rear tyre, adjust or replace the rear brake cable, and repair the horn. If he cannot do this, the moped should stay off the road. Riding as it is exposes him to police checks, fines, and possible confiscation or immobilisation, and to insurance problems if he crashes, since the vehicle is modified and defective. The mechanical risks are real: reduced braking and grip raise the chance of a loss of control, and the higher speed increases the severity of any impact. The correct judgement is that a moped that looks standard but is not compliant is still illegal and unsafe.
