Rider Profile

Best For	This is an easy, forgiving bike well suited to beginners and everyday commuters, including first-time riders.
Purpose	It's built as a rugged, low-cost workhorse for daily transport, light hauling, and utility use rather than performance riding.
Rider Fit	The low seat height and light dry weight make it accessible and manageable for riders of smaller stature or lower physical strength.
Character	It has a simple, no-frills, dependable character rooted in durability and low running costs rather than excitement.
Not Ideal For	It's not for riders seeking highway speed, long-distance touring comfort, or sporty cornering performance.

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

Feet:

At 771mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 Honda TMX 125 Alpha, with a moderate knee angle of around 110 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.
