While you've removed the data files from the current head, those blobs are still in the Git repository, making for a large clone. It would be better to rebase and alter the repo history by dropping commits c5821ab, 25bab76, 5685905, and 1576c5f. Should look something like the following:
$ git rebase -i be56342
(In your editor, delete lines 1, 4, 8, and 9)
$ git push -f
