Today a black very large two headlight japanese sports motorcycle pulled up behind me to race. When he got even, we started at 25mph and I immediately took a 6 foot lead, by the end of the GT's first gear he was ahead of me by his front wheel, after a quick shift into second I again took a 2 or 3 foot lead, by the end of second he reversed things and again took a small lead and as I shifted to third he stopped accelerating and I shot passed him. I had the feeling that I would have reeled him back in at the beginning of third (I was pulling very hard at that shift). I was surprised to realize that the beginnng of my gears left me with a lead on the bike and at the higher RPMs he seemed to gain. I was surprised because the car feels like it pulls harder at the high RPms by the "seat of my pants" test. I felt good with the results because the motorcycle was probable capable of a 10.5 second qtr mile and I was able to hold my own through the midrange.
