Rider Profile

Best ForThis bike suits riders who have moved beyond a beginner license and want a revvy, high-revving inline-four to master rather than a torque-heavy machine that does the work for them.
PurposeIt's built for spirited street riding and weekend backroad carving where its high-revving four-cylinder character and light weight shine more than raw straight-line power.
Rider FitThe low seat height and light dry weight make it very manageable for shorter or less physically strong riders, including those new to bigger displacement bikes.
CharacterIt rewards riders who enjoy the mechanical sound and smoothness of a small-capacity inline-four spun to high RPM rather than short-shifting for low-end torque.
Not Ideal ForThis isn't the right bike for riders wanting effortless highway overtaking power or long-distance touring comfort with a passenger and luggage.

2006 Honda CB 400 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 2006 Honda CB 400 Super Four, with a moderate knee angle of around 115 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.
