At 1/12 scale this model measures 6 inches from the edge of the back tires to the edge of the front tires. The width is 3.75 inches from tire to tire and 3.5 inches high from ground to the top of the handle bars. 

The model has some suspension movement on the front and back wheels. The box makes it clear to label the model as "Diecast metal with plastic parts" since it seems that most of the mode is made of plastic with only minor sections made of metal. 

These models are really well made and at this level of finishing and detail. The wheels are made of plastic and can roll.

These models come in a window box. 

These are not toys, these are display models recommended for 14 and older.
