Hi, I was racing in the Knockhill Race club preinjection 600 race series Sunday 3rd June, when I, unfortunately highsided out of the race at approximately 120mph on the back straight at Knockhill. I was wearing Knox handroid gloves, a knox aegis back protector with Knox chest protector, and knox padded impact shorts. I am happy to report that although knocked out cold…. I had no upper or lower torso damage, due no doubt to the excellent protective qualities of the knox body armour. I am also pleased to report that I sustained no hand/digit damage thanks to the handroid gloves.  It is remarkable that despite the speed and ferocity of the accident I emerged relatively unscathed thanks to my knox protection!  Gerry, via email

I’ll be purchasing a new knox back protector and shorts, as I was cut out of these at the trackside, and I wont be going racing ( or when I ride on the road) without Knox protection!

Hi,  I'm a big fan of your protection gear and was using the Knox Ageis back protector and the Sport chest protector. On my FIRST ride with them on a car pulled out infront of me and long story short, my bike (07 zx6r) was left snapped in half and I was left in hosptial over Christmas! Paramedics are saying YOUR back protector probably saved my life and I'm inclined to agree as theres quite a bit of damage done to it considering it was strapped to me!  Rory, Dublin

After getting up off of the tarmac after my big crash at Brands Hatch i was expecting my hands and body to be pretty beaten up but i believe my knox gloves and back protector stood up to the job.  I hit another bike at over 100mph and got sent flying down the track but didnt have so much as a cut or bruise on my hands.  Thanks to knox for supplying me with the best protection possible!!  Dan Cooper (Dan wears Handroids & Aegis back protector).

"One of my crashes was a high side in the rain. The long travel suspension on my KTM compressed, then extended throwing me to a great height which I came down from flat onto my back. The protector covers my back, is comfortable, fits very well and has done its job."Jon Pearson, Superbike

"I bought the new Aegis Back Protector and have been using it for approximately 2 weeks now and had to email you and tell you about it! While I haven't (and hopefully never will) have to test it, I feel completely safe with this protector on. It is light-weight, comfortable, and gives me peace of mind.  The straps around the waist help give my lower back support while I am on longer rides. I looked at the protector and saw the vents on the back and thought that they were a joke; man was I wrong. We have hit over 100 degrees a few times in the last couple weeks and I can feel the air flowing between my back and the protector even though I have it strapped down nice and secure!  I love this protector and don't ride without it. I have every confidence that if I ever were to crash it would do its job. Thanks for helping keep me safe and giving my mom and friends peace of mind while I ride."  Jason Webb Mesa, Arizona, USA

 9 days ago i was out for a ride on my 636 with some friends, after about 3 hours into a ride, i suffered a high-side. To this moment no one knows why. Anyhow, i was thrown a good 7 feet in the air and into 2 cars. After a visit to the hospital i found out i have 2 broken vertebrae. I was wearing your KNOX AEGIS back protector. This is the simpler story as to what happened to me, but im writing to say if i was not wearing it i would be definitely paralyzed or worse. So thank you for providing bikers with fantastic safety equipment.  Cheers, Kyle, W Midlands

In August 2010 I was involved in a crash on my motorbike at 60mph into the side of a car that pulled out on me. I was very lucky to survive and I am still in recovery with further operations ahead. My Bike and most of the equipment I was wearing were destroyed. My HJC helmet was smashed front and back but held together.  The only piece of equipment to survive was my Knox Aeigis back protector and it did a great job as I landed on my back further down the road. My back was one of the few places that was un-injured.  I suffered Multiple fractures to my right leg including an open fracture, a cracked sternum, bruised liver and kidneys and two bleeds on the brain. There were several other injuries but those are the main ones.Knox guys, good job on the safety equipment. Please pass that on.  Justin, Aberdeen

I would just like to thank you for the production of your excellent aegis back protector. A couple of months ago i had a head on impact with a car that pulled out directly in front of me. I bounced on the bonnet and over the car, landing flat on my back on the other side. Speed of 100kph approx. Along with my triumph leathers, your aegis protector saved my life. THANKS!!!!!!! The police attending the scene (all bikers) asked about the protection I wore and were very impressed by my lack of serious injury.  Thanks again, Duncan

Well what can I say about my Knox protection? As always before the ride on went the trusty back protector and my Handroid gloves! Off we go around Leicestershires roads on a Sunday morning for a blast with the boys until on the way back a notorious hairpin catches me napping for just a second and I'm picking myself out of the ditch after a 20mph off, the kit performed faultlessly and I was at work within the hour with no injuries just a dented wallet due to a smashed nosecone!
Keep up the good work Knox! And remember everyone WEAR the kit one day it could just save your life! GAZ, HG Leics

“The Knox back protectors are exceptional, very comfortable, fit well but are also easy to find the optimal fit with all the adjustments unlike some of the competition.  Most importantly, having recently had a big accident where I broke bones in other parts of my body, the Knox Aegis back protector allowed me to walk away with no problems whatsoever with my back.  Thanks Knox!”

"When i changed to the Knox Aegis Race earlier this year the first big difference over previous back protectors was the fit. With a wide range of adjustability i was able to set the Aegis  so that it stayed in place without compromising the fitment of the leathers. As we ride the whole spectrum of bikes around the world and in different makes of leathers, this flexibility is important and very noticeable after 9 hours in the saddle. The Knox Aegis certainly makes my job safer and more comfortable" California Superbike School
