What Buyers Should Know
Rare 4-Cylinder 400cc
The ZX-4RR is one of the only 400cc inline-4 motorcycles on the market, revving to 17,000 RPM — a feature previously only found on larger superbikes. This makes it extremely unique and desirable in its class.
Strong Resale Value
Due to high demand and limited production allocation, the ZX-4RR holds its value exceptionally well, often selling near or above MSRP on the used market. Buyers should expect to pay a premium even for slightly used examples.
Watch the Heat Output
Owners commonly report significant engine heat directed toward the rider in stop-and-go traffic, which can be uncomfortable in warm climates. This is a known characteristic of the inline-4 design, not a defect, but worth considering for daily commuters.
