Rider Profile

Best ForThis bike suits newer to intermediate riders thanks to its automatic dual-clutch transmission removing manual clutch and gear-shift demands.
PurposeIt is built primarily as an accessible, easy-to-manage commuter and everyday naked bike rather than a performance or adventure machine.
Rider FitA moderate 755mm seat height combined with a 195kg dry weight makes it manageable for most adult riders, though the weight is a bit more than a typical 400cc manual naked due to the DCT hardware.
CharacterThe inline-four engine gives a smooth, revvy delivery with a distinct high-RPM character uncommon in this displacement class, paired with the convenience-focused automatic transmission.
Not Ideal ForThis is not the right choice for riders seeking off-road capability, serious long-distance touring comfort, or a traditional manual-shift riding experience.

2017 Honda CB400A Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 755mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2017 Honda CB400A, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
