Rider Profile

Best ForThis bike suits new or returning riders who want a light, approachable machine to build confidence on.
PurposeIt is designed primarily for urban commuting and playful city riding rather than long distance or high speed use.
Rider FitThe low seat height and light dry weight make it very manageable for shorter or less physically strong riders.
CharacterIt has a sporty naked streetfighter look with premium touches like an upside-down fork and TFT dash despite its small displacement.
Not Ideal ForIt is not suited to riders wanting sustained highway speeds, long touring distances, or off-road capability.

Rider Fit Visualizer

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

Feet:

At 810mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2026 Fantic Stealth 125, with a relaxed knee angle of around 120 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.
