Rider Profile

Best ForThis bike suits riders who have moved past absolute beginner status and want a smooth, high-revving machine that rewards smooth throttle and gear use.
PurposeBuilt primarily for engaging back-road and urban sport riding, with its charm coming from a free-revving inline-four rather than outright power.
Rider FitA manageable, moderate seat height and light dry weight make it accessible to a wide range of rider sizes without feeling intimidating.
CharacterThe CB400 Super Four is a precise, mechanically refined naked sportbike that delivers its thrills through a silky four-cylinder engine and confident chassis rather than brute force.
Not Ideal ForIt is not the right choice for riders seeking long-distance touring comfort, large-capacity torque, or any off-road capability.

2014 Honda CB400 Super Four 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 2014 Honda CB400 Super Four, with a cramped knee angle of around 65 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.
