This was a nice replica windshield to replace my original Lexan HD 58181-78 for my 1976 FLH with bat wing fairing. Fit was very good, holes and slots were in the right places to transfer the OEM chromed bracing straps. Now the bad part - the windshield will not tolerate speeds in excess of 60mph, it deforms and bends down the middle from wind load, sending a funnel of air right on you and your head / helmet. Really disturbing that the distributor V-Twin allows such a sub-par design from an import supplier to be sold. I don't believe this is Lexan polycarbonate like the OEM, I do think this is acrylic plastic. If you're looking for a static display on a museum exhibit - it's a good replica. If you actually ride your bike - don't take a chance with this windshield - it is inferior. A true waste of money. I will contact MYV-TWIN about this - they are good people and they may take it back given the clear design issue we have here.
