How this is worked out: eligibility below is calculated from each motorcycle's published power and weight specs, not an official legal determination. EU/UK A2 uses the real formula (≤35kW, power-to-weight ≤0.2kW/kg) but can't account for factory-restricted variants of a more powerful base model. Australia's LAMS scheme is officially an approved list, not a pure formula - the power-to-weight ratio shown (≤150kW/tonne) is a strong indicator but always check the current state LAMS list before buying. The US has no federal beginner power cap, so those picks reflect commonly-recommended low-power specs, not a legal requirement. Always confirm current rules with your local licensing authority.
