The power rule for class A2

A class A2 motorcycle may have at most 35 kW and at most 0.2 kW per kilo. It may be restricted from a more powerful bike, but not from more than twice the power, so at most 70 kW originally. Power and weight are in the registration certificate, so you can check whether a bike fits A2.

Example

A bike has 35 kW and weighs 190 kg.

$\dfrac{35}{190} \approx 0.18$ kW/kg, which is below 0.2. It can be ridden with A2.

If you buy a restricted bike, check that the restriction is documented and in the registration certificate.
