Show the correct answer
Correct answer
A. the kerb weight of the motorcycle; however, it must not be larger than 100 kg.
Explanation
The question is about the mass of a trailer pulled by a motorcycle. The actual total mass of such a trailer must not exceed the unladen mass of the motorcycle, but not more than 100 kg - answer A.
The Road Traffic Act states that the actual total mass of a trailer pulled by a motorcycle or moped must not exceed the unladen mass of the motorcycle or moped, but it must not exceed 100 kg. So two limits apply at once, and the lower one decides: a light motorcycle with an unladen mass of 90 kg may pull a trailer weighing at most 90 kg with its load, and a heavy touring motorcycle with a mass of 300 kg - still only 100 kg. Answer B applies to a motorcycle the rule for passenger cars (where the limit is the actual total mass of the towing vehicle), and answer C distorts the rule for lorries over 3.5 t, where the mass is increased, not decreased, by 40 percent. A motorcycle has less grip and a short wheelbase, so a heavy trailer would push it on bends and when braking. In addition, the length of the combination must not exceed 4 m, and the trailer carries a number plate transferred from the motorcycle.
