Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a very large, heavy touring machine at low speeds and in traffic.
PurposeBuilt for long-distance highway touring in maximum comfort with a passenger and full luggage rather than for spirited or technical riding.
Rider FitRiders should have decent height, strength, and confidence handling substantial weight at parking-lot speeds, though the low seat and relaxed ergonomics ease long days in the saddle.
CharacterA big-twin American bagger with a thumping 116 cubic inch engine, deep torque, and a commanding, cruiser-styled presence for riders who want stately power over outright speed.
Not Ideal ForNot a good fit for new riders, off-road enthusiasts, or anyone seeking a light, nimble bike for tight city streets or aggressive cornering.

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

Feet:

At 673mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Indian Roadmaster Dark Horse, with a cramped knee angle of around 75 degrees and a slightly forward 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.
