Rider Profile

Best ForThis is an entry-level machine well suited to beginners, learners, or those riding on a restricted license.
PurposeIt's built as a simple, affordable commuter and learner bike for low-speed urban riding rather than performance or adventure use.
Rider FitThe low seat height and light weight make it accessible and unintimidating for smaller or less experienced riders.
CharacterIt's an unpretentious, low-powered single-cylinder allrounder that prioritizes approachability and economy over excitement.
Not Ideal ForThis bike is not suitable for highway touring, serious offroad work, or anyone seeking strong acceleration or high top speed.

2020 AJS Isaba 125 Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 AJS Isaba 125, 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.
