Used Buyer Review

The CB400 is one of those rare bikes that genuinely deserves its legendary status in Japan and across Asia. The VTEC system kicks in around 6,500rpm and transforms the motor from a smooth commuter into something genuinely exciting — it's not a gimmick, it actually works. Build quality is exceptional for the class, and these things run forever if maintained properly. Finding one with good history isn't hard because owners tend to treat them well. Used examples vary wildly in condition though. Watch for VTEC solenoid issues on higher-mileage bikes — symptoms are a flat spot that never resolves regardless of revs. Check the frame around the steering head for any stress cracks if the bike's been dropped, and inspect the fairings carefully because replacement plastics are pricey to source outside Japan. A well-specced Super Four with full service history is worth paying a premium for.
