Generate a motocross jersey design that embodies a blend of modern and aggressive aesthetics. The jersey should be vibrant and eye-catching, featuring elements that reflect the speed and adrenaline of motocross racing. Incorporate unique patterns and motocross-related symbolism, such as helmets, wheels, and tracks. The design must be set against a black background to highlight the brightness and details of the jersey. Ensure the layout is suitable for a jersey template. | Photo
