Rider Profile

Best ForThis bike suits new to intermediate riders who want a relaxed, low-stress classic riding experience without dealing with intimidating power.
PurposeIt's built for leisurely retro-styled cruising and short scenic rides rather than performance riding.
Rider FitThe low seat height and mild power make it manageable for riders of most sizes and modest physical strength.
CharacterIt has an old-school single-cylinder thumper charm with classic looks, a peashooter exhaust note, and unhurried, easygoing manners.
Not Ideal ForIt's not for riders seeking highway-speed touring, sporty cornering performance, or any serious off-road capability.

2020 Benelli Imperiale 400 Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Benelli Imperiale 400, 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.
