Rider Profile

Best For	This bike suits an intermediate to experienced rider comfortable with a torquey V-twin and sportier ergonomics.
Purpose	It's built for covering long distances quickly and enjoyably, blending sport-bike performance with genuine touring capability.
Rider Fit	A moderately tall seat height and a lean-forward but not extreme riding position demand reasonable fitness and inseam length.
Character	The Ducati ST4 rewards riders who want Italian V-twin character, strong midrange torque, and confident handling on twisty roads.
Not Ideal For	It's not a good fit for beginners, short riders, or anyone seeking a relaxed upright cruiser or off-road capability.

Units

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2003 Ducati ST4, with a cramped knee angle of around 70 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.
