How much is a zx4r in the US?

I'm curious, could you please clarify what exactly you mean by "zx4r"? As far as I'm aware, this doesn't directly relate to cryptocurrency or finance. However, if you're referring to a specific product or asset, perhaps you're asking about the price of a Kawasaki Ninja ZX-4R motorcycle in the United States? If that's the case, the price of a Kawasaki Ninja ZX-4R can vary depending on factors such as the model year, condition, and location. It's best to consult a reputable motorcycle dealer or check online listings to get an accurate price range for the specific bike you're interested in. If my assumption is incorrect, and you're actually asking about a different asset or product, please let me know so I can provide a more relevant answer.
