Rider Profile

Best ForThis bike suits experienced riders who are comfortable managing a heavy, high-torque V-twin with a fat rear tire and aggressive geometry.
PurposeIt's built as a premium power-cruiser that blends muscular straight-line performance with boutique, hand-built craftsmanship rather than outright track ability.
Rider FitThe low 800mm seat height aids reach to the ground, but the substantial 255kg dry weight demands confident low-speed handling and upper-body strength at a stop.
CharacterExpect a bold, exclusive machine with a thumping V-twin character, premium Ohlins suspension, and top-shelf componentry that rewards a relaxed but assertive riding style.
Not Ideal ForThis is not the right choice for new riders, off-road adventurers, or anyone seeking a lightweight, nimble commuter.

2023 Arch 1S Rider Ergonomics Assessment

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

Feet:

At 800mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2023 Arch 1S, with a relaxed knee angle of around 135 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.
