Coming from another discussion about leather and textiles. Is there any AMA or FIM approved road racing textile/near mesh material? | ||

Never seen it allowed in AMA rulebooks but I haven't seen the FIM rulebook. In fact most track day groups require full leathers for Class 1 riders (and they don't go as fast as AMA / WERA / AFM etc.) Download the rulebooks... | ||

I can't help but think that an acceptable Kevlar suit with all the required armor is going to be any less expensive than leather (and likely MORE expensive) Also, Kevlar doesn't do well in direct sunlight - it is very sensitive to ultraviolet damage - unless coated or otherwise prevented from "seeing" the sun.

So how do they get away with that "hump" on the back of modern racing suits, as any moron can see that they're there exclusively to smooth out the airflow from the rider's head over his/her back?? | ||

The hump (it has been argued) also serves to reduce injuries to the upper spinal column. I can attest to that after my high-side when I ended up having the whole bike land on top of me, cracking the helmet and 3 ribs and snapping the spinous process (the "fish fins") of the C7 and T1 vertebra. Neurologist said that if I hadn't had the padding there, I'd have been paralyzed from the chest down. (Message edited by slaughter on July 11, 2009) | ||

See here for some info on kevlar bike gear. http://www.motoport.com/ Kevlar - Kevlar is the strongest fiber known to man. Kevlar is made by Dupont and for apparel use comes in a thread form. In a pure weave Kevlar does not stretch and is not suitable for use in motorcycle apparel where abrasion is important. Cycleport makes suits from a Kevlar/Dynatec/Lycra weave. this specially blended Kevlar material meets and surpasses all requirements for motorcycle apparel. Cycleport's Kevlar suits are the only synthetic apparel approved by the F.I.M., the A.M.A., the W.E.R.A. and many other racing organizations. Cycleport also uses a Kevlar/Dynatec blend call Mesh Kevlar. All of the Mesh Kevlar Gear provides the ultrimate in protection and versatility | ||

Dang slaughter how do they fix it?  | ||

"how do they get away with that "hump" on the back of modern racing suits" I've had it explained to me that the hump is not technically defined as a separate "device", is in fact part of the suit, and is not *solely* for reducing aero drag. Yeah, seems like a stretch, but its obviously an accepted stretch. Leaves one to wonder, what device *would* fit the rule's definition? | ||

It isn't fixed, the spinous process healed as cracked (one will always be a little crooked) The attached ribs are what hurt and why I spent 4 days on morphine and dilantin (anti-seizure for the brain injury) | ||

I have also heard that an "aero hump" helps protect a rider's neck/head from hyperextension by limiting the helmet's backward movement. Considering that the foam padding protects the upper back/spine, the "hump" keeps the neck/head from whiplash/fracture, and that it is an integral part of (not attached to) the racing suit, it would appear an "aero hump" is safety equipment that's aerodynamic- not a wind-reduction device. | ||

I haven't been in a crash (thank goodness) but I think Motoport stuff is fantastic. Very comfortable, and Wayne (I believe) takes safety very very seriously. |
