A rider with an A2 licence wants to borrow a 35 kW motorcycle weighing 175 kg and originally manufactured at 80 kW. What is the key legal problem?

1. The motorcycle is too heavy for A2
2. The motorcycle's original power was above 70 kW before restriction
3. The motorcycle has exactly 35 kW
4. A2 motorcycles must always weigh less than 150 kg
