A pair of latches lock the windshield down until the spring loaded "trigger locks" are intentionally disengaged, allowing the rider to remove the windshield. Fits: 1998-2015 Yamaha XVS1100 V-Star Custom & 1998-2015 XVS650 Custom ; Kawasaki VN900 Vulcan.
While I realize the mounting hardware are for specific group applications as are the windshields. The overall cost is better than $300. A package deal of shield and hardware for around $200.
