Honda Cb400sf
The Honda CB400SF (Super Four) was introduced in 1992 as a replacement for the CB400N, featuring a inline four-cylinder engine and classic naked styling that made it an instant hit, particularly in Japan. It underwent significant updates over the years, including the introduction of HYPER VTEC in 1999, which added a valve-switching system to improve low-end torque and high-rpm performance. It remains one of the most popular middleweight naked bikes in Japan and Asia, celebrated for its smooth power delivery, quality build, and beginner-friendly yet rewarding riding character.

What Buyers Should Know
Rock-Solid Reliability
The CB400SF's inline-4 engine is renowned for lasting well over 100,000km with basic maintenance. It's considered one of the most bulletproof middleweight engines Honda ever produced.
Strong Resale Value
The CB400SF holds its value exceptionally well, especially VTEC Spec versions, often selling for 80-90% of original price after several years. High demand in Japan and export markets keeps prices consistently strong.
Watch for VTEC Solenoid Issues
On VTEC models, the solenoid valve that activates the second pair of valves at higher RPM can fail or get clogged, causing a noticeable power drop above 6,750rpm. Always test-ride and rev the engine fully before buying.
