I can see the vin tag is there on the steering neck behind the headlight. The first part of the vin is the size and style bike. Also on the right side below the carbs and by the oil dipstick will say also.
Overall appearance suggests a 750 cc model: but since I've never owned a Kawi, that's all I can add. Just a guess: without the data from the VIN tag, none of us will know......
