Depends, a picture would be helpful. My Optimate comes with a CANBUS connector which you could confuse with a cigarette connector. See image circled below. Might be what you're referring too, and it works just fine.

 

If you're talking about the port on the side of your bike, the answer is no. The bike has what is referred to as a Powerlet (DIN) socket and does not accept a cigarette lighter connector.

However, you can get an adapter from Amazon if you want to try this.

 

Yes the port on the left side of the bike. Sorry I tried to post an image it somehow it wouldn't attach. That's great thanks for the info, I wasn't aware what the port was called.

 

I have the same Ctek charger, I bought the adapter plug with 6mm eyelet connectors, connected to the battery post by the tank and the socket is tucked behind the snorkel pipe. Works a treat.
