Hey Onur,
Welcome to the forums.
I am a motorcycle Salesman at a Yamaha, Suzuki and Triumph main dealer in the UK. It could be diffrent in Australia but I doubt it, during Winter time you can push the sales team pretty hard as we are far more likely to give some really good deals in winter. Your best bet is to find a dealer that has had an FZ6R for a while in their showroom, they will be more likely to want to shift it, therefore are far more willing to reduce the price. If a dealer has only had a bike a few weeks they will try to hold out for as much as possible to get a good return on the investement. After a while dealers just want to move the bike on to freshen up the showroom for minimal profit. The other thing to do is go in on a quiet day midweek, again you are more likely to get a better deal due to low or even no sales that day. Even in Winter a dealer could sell 5 - 10 bikes at a weekend so have no need to barter as much. The other thing is go to the dealer with information on bikes from other dealers that you are also interested in, if they know you will walk to find the best deal they will do a little more perhaps.
Good look finding a bike, you cannot go wrong with the FZ6R / XJ6
