"The Hump" please explain it to me

[FROSTY:Me]

I know the thing with race leathers nowadays is to have a "hump" between the shoulders.
Maybee I'm just too oldskool but I just dont see the point of it.
In a crash Instead of a flat surface to sppread the load you've got a big lump to roll over.
For aerodynamics I can kinda gettit for a 125 racer but I'da thought a bigger bike woulda been better with a flat back
So wazzit all about?

Aerodynamics. Also, good spot for a hydro pack etc for endurance racing.

Its there so that when you have finished racing, and you unzip your leathers down to the waist, you have something compfy to sit on.

A great place to stash your lippie!

I figured they help with neck pressure at high speeds.

It stops your head from bending to far back, ie the helmet stops against the hump, reducing spinal (Neck) injuries....and as a back protector by spreading the load of an impact

This is what I heard as well.

I have no idea why the hump, but did expect Frosty and Shaun to know.
Is this a troll?

Not at all mate! Frosy ? was genuine, and I also agree with his comment re the potentuall disaster of them as far as making you roll around on the ground

'the hump'

come 'round to our place and the staffy will explain it to your leg....

[paturoa]

You mean like this?

[Gwinch]

I thought it was purely for the irony of the "Quasimoto" logo on my back.

[Peter Smith]

It is to help the air flow move around the helmet more smoothly while going flat out down a straight.
Without it a pocket of low pressure develops behind the helmet and causes the helmet to be pushed around. (You get a sore neck and may have trouble spotting your braking point)
You only really notice the difference when you start going over 220 km/hr.

Twice i've gone into the gravel trap at speed and managed to land on my back while moving headfirst.............bloody hump bit into the gravel and stopped me instantly, too fast for me poor ole neck. Hasn't come right since.

Tis a good place to keep yer smokes during a race though
