Is 1000cc too much for a 1st bike?

This weekend, I told my dad about an Indian Scout 60 that I found at a used motorcycle dealer that I was interested in. He then asked me how many cc’s it had, I said that it had 1000cc. Upon hearing my answer however, my dad told me that 1000cc was too powerful for a 1st motorcycle, especially considering that I have no riding experience other than the Basic Rider Course I enrolled in last June. Is he right?
