Drive right…….

Hi guys! I drive a 92 GSX600F (Suzuki) with Bridgestone Battlax BT-021 in the dimensions 110 front and 150 rear. Actually, according to the report, the tire should be quite good on the internet. Now to my problem: I have on my tires outside still a margin of about 1 cm and I have the feeling that I don’t come down further, or lie down if I try it further down. If this is on the motorcycle, the tires are not as good as described, or am I just to d oof zum fahren??? So as I said, I personally didn’t feel like going further down, as I always feel that my “old” starts to slide when I try to get further down. Who can help me there further, or give me helpful tips?! Would like to use the tire completely, since I also have to pay it completely Many thanks already in advance, M.Fleue……
