the blue one is mine and im 6 foot 4 to be honest I fitted it for the looks sad I know but got a adjustable add on on my tdm and its a waste of space looking to get another screen
same speed and could not tell any difference. Couldn't be arsed to put the OEM one back on and sell the D/B so kept the OEM as spare.
The D/B looks better I thinkHere is a picture of mine, if you look at the end of the actual fibreglass fairing you can see that the screen starts flush the end, now have a look at other forcers bikes and you will see that some D/B screens start past the fairing and are more aggressively upright than mine which I think is the reason mine is not so effective.
I brought mine second hand - maybe the fella sold it for the same reason, the make is something like nuVo but the name has long since been polished off.
I don't mind the wind blast as IMO its all part of the experience - feeling the air. ( I am 5'8" ) but have longer arms than my height would suggest so I may be sitting slightly more upright to start with.
Now look at this foccers blue bike it looks like the D/B screen is at least 2 inch higher that the end of the fairing and more agressivly angled.
