Speed hump on leathers?
 
Thinking of getting some nice and shiny leathers, and just wondering whether or not to get a race hump fitted; is there a noticeable drop in wind resistance at speed? Enough to warrant the extra problems in the case of an accident?
Thanks!

A racing instructor told me they're good for 2 or 3 mph when a bike is doing about 160+. So basically they're just for show on the road. Don't know how they affect turbulence though. May help some.

They can cause discomfort, like mine did so I got it removed.

Also not great if you have a short neck I have seen helmets been pushed forward by the hump

i agree with the uncomfortable argument but it no longer bothers me. Can get annoying when you have a back pack on.

however, it does make you look incredibly cool and like you know what you're doing at trackdays ect.

That's a speed hump?

I thought you were just a hunchback Gav.

I've got an RST tractech jacket and I've taken the foam out of the aero hump as it was restricting my head movements. Head pushed forward too.

I thought a speed hump was something members of the GM did in IKEA wardrobes. Or am I getting my threads mixed up?

I think they are hilarious and make one look like a pillock.

Even on the track, they are of extremely limited use in terms of performance gains. The main advantage is that ones will a hollow 'void' in them provide a convenient place for a camelbak resevoir for endurance racing, or, if you're into that sort of thing, telemetry kit. On the road? 100% show/fashion. Still, no harm in that if you like the looks. The cruiser crowd don't exactly dress the way they do for functionality. ;)

Brilliant :D

Think I'll give it a miss then. Dug up an article I read a while back and apparently they can be problematic in an accident.

The airway and (cervical and thoracolumbar) spine cannot be managed effectively in the helmeted patient with a speed hump in place and intubation by direct laryngoscopy is almost impossible with a speed hump in place.
Not that you'd particularly want a laryngoscopy, they feel sh!t :p
