I don't think BigE has to worry about bullets going through his screen. I know it's a German bike but, c'mon, we're all friends now.

I call BS on the lower penetration rate of Perspex.

Anti shrapnel shields are made out of lexan?
Lexan is a type of polycarbonate
"These are not machines for the meek. Ride it like you stole it, cane it within an inch of its life. It will require a bunch of maintenance and generally tend to be, shall we say, harsh? It was bred for racing, after all. It will devour rear tires and its lust for fuel will astound you. It will suffer indifference and carelessness very poorly. Like heroin and Asian girls, it's not for everybody, but when you absolutely, positively, GOTS to beat every m*****f****** in the race, accept no substitu

So everyone agrees.......perspex is no good!!!
I made a perspex screen for my KLE , had a minor fall and that perspex shattered into shards that could kill a person.
That is the real problem when Perspex breaks it shatters into very sharp shards.

Those Shatterprufe rulers from when we were kids, they are made from Polycarbonate. They way those rulers break is how Polycarbonate goes. Also a stone will be deflected by a PC screen and will probably come straight through a Perspex screen.

The above videos show the truth of it. Interestingly yes various shops try and sell PC as Perspex. They don't understand the difference. Perspex will always shatter under impact. That is a nature of Acrylics. It is hard to mould as a result.

Perspex is a trade name for clear Acrylic sheet. It has the ease of manufacture and all the other advantages but also has all the disadvantages of Acrylic. Perspex will always shatter under impact or big deflections. That is a nature of Acrylics. It is hard to mould in complex shapes as a result. Its true advantage is its optically clear characteristic. On your car the speedo cover, tail-lights and most indicators are in Acrylic.

Polycarbonate is a a different material all together and is very good at ballistic protection.  It can be opaque like the BMW and Toyota Bumpers of the 80's. Or clear sheet as per Helmet visors etc. Nowadays car bumpers are in easier to produce PP but car headlights are PC.
