Using sed command in for loop across multiple servers

I am trying to manipulate the same text file across multiple hosts. The command I currently have it:

for host in $(cat /etc/hosts | grep text | cut -d' ' -f 1 | sort -u); do
    ssh $host \
    sudo sed -i "s/enabled = 1/enabled = 0/" /etc/yum.repos.d/testing.repo
done

The sed command itself works locally on the host with no problems however when I run it here, I get:

sed: -e expression #1, char 9: unterminated `s' command

What am I doing wrong?
