"The frontal lobe is not involved in motor skills"?
The frontal lobe is interconnected and IS involved in motor skills.
"Frontal lobe -- The frontal lobe is involved in motor skills (including speech) and cognitive functions.
The motor center of the brain (pre-central gyrus) is located in the rear of the frontal lobe, just in front of the parietal lobe. It receives connections from the somatosensory portion in the parietal lobe and processes and initiates motor functions. Like the homunculus in the parietal lobe, the pre-central gyrus has a motor map of the brain (for details, see A Science Odyssey: You Try It: Probe the Brain Activity).
An area on the left side of the frontal lobe, called Broca's area, processes language by controlling the muscles that make sounds (mouth, lips and larynx). Damage to this area results in motor aphasia, in which patients can understand language but cannot produce meaningful or appropriate sounds.
Remaining areas of the frontal lobe perform associative processes (thought, learning, memory)."
