So in the end your tire size will offset the sprocket by roughly a little over 2 teeth, so it'll be like you running a 41+ sprocket instead of the 40 stock. In reality you gain a touch more low end(may not even notice) and lose approx 4mph top end theoretically.
@ 10,500 rpm GC is saying:
How does that big ballon tire handle hot in the corners
Stock tire w/larger sprocket 170.9
Stock tire stock sprocket 183.7
200/55 tire w/16/43 sprocket 179.1
200/55 w/stock sprocket 192.5
Of course speculative speeds.
