Description
Gain a race-inspired look by upgrading your Kawasaki ZX-4RR / ZX-4R with our high-quality Undertail Closeout that covers the gap left behind after removing the stock fender. Each closeout is crafted from injection molded ABS plastic alloy and precision engineered to perfectly fit the ZX-4RR and ZX-4R without the need for any modification. We also wanted to ensure that this aftermarket part doesn't look "aftermarket" once it's installed, which is why we went the extra mile to color and texture match our closeout to the surrounding stock undertail panels and ensure it looks like it was installed at the factory. Not only does this improve the looks of your Kawasaki Ninja, but it also aids in keeping water, dirt, rubber, and general road debris out of your subtray. It's time to upgrade your tail section and let the race DNA of your Kawasaki Ninja ZX-4RR or ZX-4R shine.
