About National Cycle
National Cycle has manufactured motorcycle windshields in Illinois since 1937, using its own hardcoated Quantum polycarbonate. Windshield choice affects wind noise, buffeting and fatigue more than most riders expect, and National Cycle publishes real height and coverage data to get it right.
The National Cycle Switchblade windshield offers exceptional wind protection and clarity for V-twin riders. Crafted from 4.0mm thick Lexan polycarbonate with Quantum hard coating, it delivers superior impact resistance and long-lasting durability. Its quick-release design, when paired with the Quick-Release Mount Kit (sold separately), allows for tool-free removal, providing ultimate flexibility for your ride.
