The Kawasaki Ninja 400 and Z400 motorcycles remain strong in the Japanese market, where stricter licensing rules limit engine displacement to 400cc for beginner riders.
With 399cc engines, these models strike a balance between power, accessibility, and style, making them ideal for new riders or daily commuters. For 2025, the bikes retain the same mechanics from their last update in 2018 but get new color combinations to refresh their appearance.
In Japan, prices remain affordable for beginner riders, with the Ninja 400 costing around $5,110 and the Z400 about $4,825. Although these models remain in the Japanese lineup, they have been removed from Kawasaki’s U.S. range, which now focuses on the Ninja 500 and Z500 versions with larger engines and improvements that maintain the small-displacement philosophy.
So, while countries like the U.S. allow young riders to access more powerful motorcycles early on, Japan values a more gradual progression, which keeps the Ninja 400 and Z400 relevant as reliable, affordable, and fun options for beginners and urban riders.
