Rider Profile

Best For	This is a machine for experienced, confident riders given its high power output, premium suspension, and aggressive performance-oriented engineering.
Purpose	Built as a high-performance sport tourer, it excels at fast, twisty road riding and long-distance runs where speed and precision matter more than outright comfort.
Rider Fit	A relatively light, compact chassis for its power class combined with a sportbike-like riding stance means riders benefit from decent strength and flexibility, though the low-ish seat height helps shorter riders manage it.
Character	Exotic, boutique, and unapologetically powerful, this bike suits riders who want a rare American-made V4 with race-bred components and a strong sense of individuality.
Not Ideal For	This is not the right bike for off-road exploration, absolute beginners, or riders prioritizing plush all-day comfort over sporting performance.

Units

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

Feet:

At 813mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 Motus MSTR, 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.
