Final answer:
Ronald can approach the magistrate's court to ask for specific performance to compel Natalie to hand over the motorbike as per their binding contract.
Step-by-step explanation:
When Ronald buys a motorbike from Natalie for R35 000.00 and she fails to deliver the motorbike, Ronald has entered into a binding contract that has not been honored on Natalie's end. In such cases, Ronald can approach the magistrate's court to ask for specific performance of the agreement.
This is a legal remedy where the court orders the party who breached the contract to perform their part of the bargain. It is within Ronald's legal rights to pursue this action to compel Natalie to hand over the motorbike as per the terms of their agreement.
