Kawasaki Ninja 400 Review

Used Buyer Review

The Ninja 400 is probably the most sensible used bike purchase you can make right now, and I say that having ridden everything from 125s to litrebikes. Kawasaki got the formula exactly right here — 45bhp that feels genuinely quick in the real world, a chassis that'll embarrass bigger bikes through the twisties, and build quality that holds up remarkably well used. Find one with under 10k miles and you're laughing. What surprises most riders is how long the 400 stays interesting. It's not a bike you outgrow in six months like most small-displacement machines. The parallel-twin pulls cleanly from low revs, the suspension is properly sorted from the factory, and the brakes — especially the radial front caliper — are legitimately good. Check the chain and sprockets first on any used example, because owners who thrash them often neglect basic maintenance. Used prices have stayed stubbornly high because everyone knows how good these are. Don't pay over $5,500 for anything pre-2020 regardless of how pristine it looks. Walk away from any with crash damage on the fairing — they're almost always hiding bent subframes.
