A 350 kg light quadricycle has a petrol engine greater than 50 cc but is electronically limited to 45 km/h. Why is AM not automatically enough based on DGT's light-quadricycle description?

1. Combustion-engine light quadricycles must also meet the cylinder-capacity condition, not only the speed condition
2. Speed is the only feature DGT mentions
3. AM covers every four-wheel vehicle under 70 km/h
4. Cylinder capacity never matters for AM vehicles
