Rider Profile

Best ForIdeal for beginners and even experienced riders looking for a fun, low-stakes machine to hone throttle and clutch control.
PurposeBuilt for playful urban commuting, tight backroad scratching, and general grin-inducing fun rather than outright performance.
Rider FitIts very low seat height and lightweight 224 lb chassis make it extremely accessible to shorter or less physically strong riders.
CharacterA cheeky, minibike-inspired runabout that rewards flickable handling and high-rev thrashing over raw power.
Not Ideal ForNot suited to highway touring, carrying a passenger long distances, or riders seeking strong straight-line performance.

2023 Honda Grom Rider Ergonomics Assessment

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

Feet:

At 761mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2023 Honda Grom, with a cramped knee angle of around 65 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.
