Rider Profile

Best ForThis small-capacity cruiser is well suited to beginners and those wanting a low-stress, low-power introduction to cruiser riding.
PurposeIt's built for relaxed, low-speed cruising and short trips rather than outright performance or long-distance touring.
Rider FitThe low seat height and modest weight make it accessible to shorter or less experienced riders who want confidence at stops.
CharacterIt has classic cruiser styling with a shaft drive and V-twin character, favoring style and easy manageability over speed.
Not Ideal ForIt's not a good fit for riders seeking strong acceleration, highway overtaking power, or serious off-road capability.

2012 Yamaha DS4 DragStar Four Rider Ergonomics Assessment

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

Feet:

At 710mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Yamaha DS4 DragStar Four, with a cramped knee angle of around 80 degrees and an upright 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.
