Very impressed with the quality and how they fit my 2019 KX450
First off, I have to say that I'm very impressed with the quality and fitment of these radiators. Seeing that they're about a quarter of the price of 2 new OEM radiators for my 2019 Kawasaki KX450, I couldn't be happier. The fit was about 95% perfect, as the OEM radiator louvers needed to be massaged in order to fit. Aside from that, they fit and look great and being braced from the factory is a nice touch. They seem a tiny, tiny bit bigger than the factory radiators, so it should help with cooling. All in all, I'm very happy with the radiators and would definitely purchase again.
The only difference I found was the original radiator has a smaller over flow nipple but wasn’t a big deal. Kawasaki wanted nearly $800 for right and left side radiators and I bought this set for $90. I even bought a second set just in case.
