It looks to me like your bike has higher gearing than standard. (Assuming this is your FZS600 and obviously top gear). The standard sprockets, as said before, are indeed 15 front and 48 rear. A larger front and/or a smaller back sprocket would give higher gearing. i.e. lower revs for a given speed.
On my FZS600 with standard gearing I think the revs are just over 6000.
