I've only had my FZ6R for a couple weeks and I checked the tire pressure today finally. It seems that it was pretty low. And on top of that, I weigh 240 so I'm supposed to have 36F/42R. So in my case, it was very low...about 29F/33R. So I put some air in and the bike is even more amazing now. It leans a hundred times better which is awesome because I already thought it leaned nicely. Everyone check your tire pressures. I'm thinking of buying this thing:
