My questions are this. What would be considered a great 60 foot time on a box stock unlowered unstrapped totally untouched ZX12? Now, how much of a bearing does rider weight have on this number. In other words can a 120 pounder and a 220 pounder of equal skill cut equal 60 foot times? What Iam getting at is how can a heavy guy know if hes riding good or are his times are just slower everywhere because hes heavy.
