I did the math and came up with these #s. With my new ratio of 1:2.35 I should have a theoretical speed of 156Mph at my red line of 9K. The engine should be able to do it with no problem. BUT, I would doubt that the bike frame would stay on two stable wheels at that speed. After all it is essentially a 1981 1000CSR frame. It is a bit better than the KZ900/1000 frames but not that much better.
