GSA Stopping distance.

[E. Buygum]

If the bike is simply slowing in a straight line it's negative acceleration in the same plane.

Quite.

Normally the acceleration/ deceleration forces act through the tyre contact patch. The bike pivots around the centre of mass, tipping the bike's nose upwards under an accelerating force and downwards under braking. Just pivot a match box between two fingers and push at a bottom edge, the front will, of course, tip upwards when the box is pushed from behind and vice versa. The bike's suspension will compress at whichever wheel is under more than the usual weight distribution. I haven't tested it but presumably a braking force applied above the centre of mass (high branch, tightly strung piano wire...that sort of thing) would cause the rear suspension to compress, rather than the front.

"Things can slow down as well as speed up. Deceleration - slowing down - just means that the change in velocity is negative."

I'm surprised they print stuff like that in Razzle.

Dunno about the techie stuff but i had a tractror pull right out in front at somewhere around 60 that was the first time with the brakes full on
PURE BROWN TROUSER manouver road was warm/dry stopping ability is truly astonishing!!!!!!!!!! been biking a loooong time with loads o bikes but this thing
GSA12 truly has incredible stopping power
I can remenber this incident like it was 10 minuites ago the (mibbies others have had this, time seemed to slow down ) weird thing to me was, that although the machine had abs the tyres were howling in a major way just kept thinking
dont tuck it dont tuck it Scary few moments cant claim to have used any great braking skills simply hammered the lot full on
Standard tourance tyres
