Recent statistics have shown there has been a 24% increase in motorcycle deaths in the capital this year.
24 people have been killed on London roads, triggering an investigation by the London Assembly's Transport Committee into road safety.
Members of the Metropolitan Police and the Ambulance service say a lack of personal protective equipment (PPE) could be to blame.
Mark Hazelton from London Fire Brigade says the problem could be caused by people being forced to ride mopeds or motorcycles due to financial contraints, and not investing in proper PPE.
Mr. Hazelton said: "We've got a lot of riders who drive occasionally. They've been forced to ride two-wheel transport because driving a car in London isn't a go.
"Most of them don't want to put on protective leathers or clothing, they just want to bung on their helmet and go."
