It works perfectly for my teal Ninja 400 (2021). Super easy to install, just four bolts, careful not to overtighten. It really looks better in person with the way it shimmers and shifts colors.I took it for a test ride and I think it actually performs better than stock in terms of wind deflection. At roughly 65 mph on a fairly windy day (15-20mph crosswind), I felt like the wind was a lot less turbulent on my upper chest & helmet.Only downside I can think of is you can't see through it at all, but while riding it's not obscuring anything except for ~3ft in front of the tire. If anything it's actually helped visibility of the info cluster because it blocks sunlight that would obscure it otherwise. That and it took a while to arrive at my door, but it was sooner than the estimated time.3 month update: I'm legitimately surprised how scratch/chip resistant this windscreen is. After thousands of miles, I could not be happier with how this looks. Still looks just as good as it did day one. I've been cleaning it with a soft sponge and drying it off with microfiber towels, for context. Worth buying for sure!
