Most listings show two common scales for diecast dirt bike models: 1:6 and 1:12.
They are typically described as diecast metal for the main body, with many models also using plastic components.
Dimensions vary by scale. In the listings, lengths range from about 6.75 to 13.75 inches, widths from about 2.75 to 5.5 inches, and heights from about 4 to 8.5 inches.
Common suggested ages in listings include: 3 years and up, 8 years and up, and 14 years and up.
Listings commonly state the item comes in a brand-new box with the manufacturer's original unopened packaging and note that the manufacturer may change the outer box while the product remains the same.
Many listings note real rubber tires and that the wheels roll and steer; at least one listing specifies the model has no openings.
Weights vary widely in listings, from about 0.05 pounds up to around 5 pounds.
