Rider Profile

Best ForThis bike is ideal for brand-new riders, learners, and anyone riding on a 125cc license or restricted permit.
PurposeIt's built for easy commuting, urban errands, and learning the ropes rather than performance riding.
Rider FitIts low seat height and lightweight chassis make it very approachable for shorter or less physically strong riders.
CharacterA classic-styled, friendly roadster that prioritizes simplicity, low running costs, and confidence-inspiring manners over outright speed.
Not Ideal ForThis is not the right bike for experienced riders seeking motorway speed, long-distance touring comfort, or off-road capability.

Rider Fit Visualizer

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

Feet:

At 780mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 AJS Tempest Roadster 125, with a moderate knee angle of around 115 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.
