ZXR 400 kevlar engine case covers

hi all,
Ive just found some kevlar engine case covers from RB Imports. I was wondering if anyone here has them or knows of them in regards to quality and fit?
I live in Adelaide so wont be able to get a real good look at them if I buy them as ill get them posted to me!
Ive been looking for something like this for a while now and this is all ive come up with!
Thanks

I've got a set of their cases on my VFR400. I haven't had to test them as crash protection yet, but they pass scrutineering so I'm happy with them

rb imports are a great bunch of guys, everything i have get off them for my 400 has been fine and all the advice has been spot on, id trust the covers will fit fine
