KE =1/2 m v²
mass =  400kg
velocity = 60m/s
KE = 1440000 kgm/s

Missed out the bit when in your mine you think "oh sh#t" and flying out your backside to increase the KE would be.......

Probably not a factor as it would be contained by ATGATT.  :016:

119 mph, indicated, is how fast I was going when I decided it was enough for me. I try to have my fun below 80 mph. I have no idea what top speed is possible but I believe I'd remove the bags before trying to find out.

so you're saying a sudden stop would not be good?

Not the top speed I know but on a quiet Sunday on the way back from Norway this summer I held the ton for more than an hour on the autobahn two up, panniers, top box and tank bag. No drama at all, boring in fact. Tigger felt totally comfy and unstressed.
The time it got exciting was when overtaking into the outside lane where the mostly large, mostly black and mostly German cars were coming past. Fast.
One time I checked carefully before pulling out, and as I pulled back in having past a slow (99mph) car there was an almighty roar as something matt black and VERY expensive looking took off for the horizon, which he reached in very little time.
Of course I talk to myself.
Sometimes I need expert advice.

I did the ton on the Autobahn in a rented Ford Mondeo wagon back in '02. Lots of fun with the family in tow.  :018:

For Me it would be the same...

KE =1/2 m v²
mass =  400kg (250 kg bike +15kg fuel + 95 kg of me + 30 kg full panniers)
velocity = 60m/s
KE = 720000 kgm/s'
I think you forgot to divide by two

with the Missus:
KE =1/2 m v²
mass =  460 kg
velocity = 60m/s
KE = 828000 kgm/s and an :005: unhappy wife shouting... :232: :232: :232: :172: :172: :172:slow down you moron!!!!!

You're right, I forgot to divide by two.
The point remains that it is a very large number and a lot of energy to dissipate in the event that anything doesn't go to plan.

And from a probabilistic point of view, the more people reach such speeds, the more possibilities there are that something doesn't go to plan ;-)
