Bmw system 6 question

[gebrauchtwagen83]

Just about to fork out for a system 6 and wondered if there was any difference between a system 6 and a system 6 evo. Also I noticed that some helmets say BMW in large letters on the rear and some have a smaller BMW helmets logo. Are these different models or does it depend in the mood of the fella putting the stickers on as the woman at park lane motorrad has told me.
Many thanks
Dan

Differences are in the details...

I use a System 6 Evo - best helmet I've ever owned. Comfortable and quiet - way better than my Schuberth C3.

The sticker lady was using medium-sizes BMW ones the day they made mine...

It doesn't bother me but I was curious as to why different logos adorned the rear of the helmet. I didn't want to pay full whack for an older model, the funny thing is no one at the dealership or BMW uk have any idea why the logos differ! It's a complete mystery
