The rear wheels of motorcycles are typically smaller than the front wheels for several reasons. Firstly, having a smaller rear wheel helps to reduce the overall weight of the motorcycle, which can improve handling and maneuverability. Additionally, a smaller rear wheel can also contribute to better acceleration and performance, as it reduces rotational inertia. Lastly, the smaller rear wheel allows for a larger tire contact patch, which can improve traction and stability, especially during cornering. **

Ultimately, the better option will depend on the skater's skating style and the type of terrain they will be skating on. **
