'Motorrad' (motorcycle) is a compound noun made from 'der Motor' (engine) and 'das Rad' (wheel/bike). Literally, it is therefore a wheel or bike with an engine. The article 'das' comes from the head word 'Rad'.
Mein Fahrrad hat keinen Motor, es ist kein Motorrad.
My bicycle doesn't have an engine; it's not a motorcycle.
The appropriate verb with 'Motorrad' (motorcycle) is 'fahren' (to drive/ride). You say 'Motorrad fahren' (to ride a motorcycle) or 'mit dem Motorrad fahren' (to go by motorcycle).
Am Wochenende fahren wir oft mit dem Motorrad in die Berge.
On weekends, we often ride the motorcycle into the mountains.
Around the topic of 'Motorrad' (motorcycle), there are fixed expressions such as 'den Motorradführerschein machen' (to get a motorcycle license), 'einen Motorradhelm tragen' (to wear a motorcycle helmet), or 'auf dem Motorrad sitzen' (to sit on the motorcycle).
Ohne einen Motorradhelm darf man nicht fahren.
You are not allowed to ride without a motorcycle helmet.
machine
'die Maschine' can colloquially mean a motorcycle. 'das Motorrad' is the normal and precise word for a two-wheeled motor vehicle with an engine. In this context, 'Maschine' sounds more casual and often somewhat enthusiastic, for example among motorcycle fans. In official or neutral situations, 'Motorrad' is better. If someone says 'meine Maschine steht vor der Tür' (my bike is outside), they probably mean their motorcycle, but only the context makes that clear.

Nach der Reparatur läuft seine alte Maschine wieder sehr ruhig.
