We do not all have access to a dyno, but we all have a mobile phone and those who use Android can download 2 useful and free apps:
There are some laws of physics to consider, mainly the role of mass in acceleration:
1) At constant mass, acceleration is proportional to the driving force.
2) At constant force, acceleration is inversely proportional to mass.
So in this example the mass of the bike is nearabout 200KG - add to that a full tank of gas = 15 KG and an overweight rider with cloth = 115 KG
There may be other extras and farkles that add to the weight but as they are unknown between bikes we leave them out.
This shows that a lightweight rider could make the bike go about 15% faster - or 1.8 seconds. So we would then have about 10 seconds to 100kmh which is not as good as Dool but close. This is before I modified the needle. I also drive each gear to 7000rpm when an experienced race driver would find a better point to switch and I somewhat fumble the start. All of this may move the final result closer to 9 seconds.
I did 4 runs in total but only 2 where saved (I have to look into the program more closely) - 3 gave 12 seconds, one gave 13 seconds so I think 12 is more realistic as top result.
