Rider Profile

Best ForBest suited to experienced riders who understand the quirks of a rigid-frame, springer-fork custom chopper with no rear suspension.
PurposeBuilt purely as a low-slung, hand-built Harley-Davidson-powered style statement rather than a performance or practical machine.
Rider FitThe very low 660mm seat height and long, stretched riding position suit taller riders, but the rigid rear end demands a tolerance for harsh, jarring ride quality.
CharacterA boutique Japanese-built custom cruiser that trades comfort, agility, and range for radical minimalist style and old-school chopper attitude.
Not Ideal ForNot for riders seeking comfort, cornering agility, long-distance touring range, passenger capability, or any off-road use.

2016 Zero Engineering Type 5 Open Primary Rider Ergonomics Assessment

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

Feet:

At 660mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2016 Zero Engineering Type 5 Open Primary, with a cramped knee angle of around 70 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.
