Aluminum is a popular material for dirt bike wheels due to its lightweight and strength. Here's a breakdown of its characteristics:

Lightweight: Aluminum wheels are significantly lighter than their steel counterparts, which can improve the bike's acceleration and maneuverability. This reduction in weight also contributes to a lower center of gravity, enhancing the bike's stability during high-speed turns and jumps.

Strength and Durability: Despite being lightweight, aluminum wheels are known for their strength. They can withstand the rigors of off-road riding, including impacts and abrasions from rough terrain.

Heat Dissipation: Aluminum has good heat dissipation properties, which is beneficial for maintaining tire temperatures during intense riding sessions, thus reducing the risk of tire blowouts.

Cost-Effectiveness: Aluminum wheels are relatively affordable, making them accessible to a wide range of riders.

Steel is a traditional material for wheels, and its properties include:

Durability: Steel wheels are renowned for their durability and resistance to deformation under heavy loads and conditions.

Cost: Steel is a more economical material compared to aluminum, making steel wheels a cost-effective choice for riders on a budget.

Weight: While steel wheels are heavier than aluminum, the added weight can provide a smoother ride due to the material's ability to absorb impacts better than aluminum.

4. Maintenance: Steel wheels are less susceptible to corrosion compared to aluminum, although they may require more frequent cleaning to prevent rust.
