That's some impressive testing, not to say I wouldn't have expected this but it does help to see what goes on behind the scenes since you not always see it. Thanks for posting the video.
I don't and won't risk it. Riding in the city can be very dangerous with all the horrible drivers, if I was to get hit, having the most protection around a vital area is a must. Plus on a bike like the G310R a sporty full face goes with the bikes themeDoes anyone use a non-full face helmet while riding? Is it true that anything but those are basically not very safe at all?
