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. **

The cost difference between the two types of wheels can vary depending on the specific design, size, and brand. **

No, you cannot replace longboard wheels with skateboard wheels. Longboard wheels are typically larger and softer than skateboard wheels, allowing for a smoother ride and better stability at higher speeds. Skateboard wheels are smaller and harder, designed for tricks and maneuvers that require more precision and control. Using skateboard wheels on a longboard could result in a less comfortable and less stable ride. **

The choice between 80mm and 100mm wheels depends on the specific use and preference of the skater. 80mm wheels are generally better for maneuverability and agility, making them suitable for tricks and urban skating. On the other hand, 100mm wheels are better for speed and stability, making them ideal for long-distance skating and cruising. Ultimately, the better option will depend on the skater's skating style and the type of terrain they will be skating on. **
