Hope this don't offend anyone as that is not my intention. I've seen it here, on other forums, & even in conversation at places were riders gather and talk. I always see people referring to their over all total height (head to foot) when referring to how handle bar height and windshield height is right for them and what seat they want.
Some one will always say I'm 6ft and your 6ft so the height windshield I have will work for you. It rarely works out that way as it is almost impossible to find 2 people that their measurements are exactly the same and that sit in the exact same position as they ride. Some sit straight up and some slouch.
An example of this is my son and I are both exactly 6ft tall standing side by side. Sitting down my son is taller than me. I have a 36in inseam. My son has a 32in inseam. So sitting on my bike in my normal riding position a wind shield that fits me right is to short for him. One needs to figure ones height from their head to their butt while sitting in their normal riding position on their bike to determine what height windshield they need.
Their height from head to foot makes no difference at all. Also what seat one may have on their bike is a factor.
You can take 2 identical Harley Ultras except they each have a different seat. How thick that seat is on them also makes a difference. Even a 1in difference in the seat thickness can have a big effect on which windshield is the proper height. Also I see many that ride different bikes. In many cases with different bikes there is a difference between the seat height and the height where the bars mount on top of the triple tree and also where the windshield mounts. I know that sounds dumb but I've seen people do it.
Now my arms take a 35in sleeve. My sons arms are a couple inches shorter than mine. Arm length also can make a big difference as far as what seat or handle bars will fit a person right and also ones leg length comes into play too as far as what seat one is comfortable on. I'll use 6ft just as a number to use here as that is where my son and I are at.
A person 6ft tall with shorter arms and/or legs may need a seat that moves them forward some or a set of bars with more pull back. One with longer arms and/or legs may need a seat to move them back some or bars with less or no pull back. There fore ones over all height makes no difference again.
Over my years I've seen people spend money on these parts because Joe is the same height as me and it fits him, mount them and then find out that the part is no where close to being the right fit for them.
I have my trike set perfect for me. There is a big difference in being comfortable and well it's ok and it really makes a difference on those long rides.
Again I hope I haven't offended anyone I just wanted to put this info out so others realize that theres more to getting their trike or bike to fit them right the way they want it too and maybe save some bucks in the process not buying the wrong part. I did considerable research and checking in order to get mine exactly right for me and I managed to do it with out spending money on the wrong parts. Just remember ones over all height has no bearing at all when trying to find the right part that will fit you right. I hope everyone gets what I'm saying. Sometimes I don't type things as well as I think them.
