Rider Profile

Best For	Suits riders who have progressed past a beginner license and want a torquey, low-slung V-twin cruiser without a huge learning curve.
Purpose	Built for relaxed boulevard cruising and weekend rides where laid-back style and V-twin character matter more than outright performance.
Rider Fit	The low 675mm seat height and low-slung cruiser stance make it accessible for shorter riders, though the 244kg dry weight demands some confidence at low speed and standstill.
Character	A classic custom-cruiser feel with a punchy DOHC V-twin, belt final drive smoothness, and enough midrange torque to feel muscular without being intimidating.
Not Ideal For	Not the right choice for riders wanting sharp cornering agility, off-road capability, or serious high-speed sport performance.

Inseam (optional)

Units

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

Feet:

At 675mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Hyosung ST7, with a cramped knee angle of around 75 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.
