There has been some discussion on these posters. They're pretty much all 'illustrations' of one form or another - these are not vintage photographs, so don't expect details to be perfect or accurate.
It will likely look like studio-shot images of guys posing on motorcycles overlaid on photographs of roads, with blurring etc. added along with other digitally added details.
Lean angles etc. won't necessarily look right, nor will the details on the bikes. I mean really, if you're dragging knees on an old CB550 (which is what the bike in that pic looks like) you're not going to still have frying-pan turn signals mounted on the bike nor the stock huge chrome fender, or frankly even a headlight.
Anyhow - buyer beware - know what you're getting when you order one of these and do some Googling on in to get some opinions.
