Rider Profile

Best For	This is an ideal machine for new riders or learner-licence holders who want cruiser style without intimidating power.
Purpose	It's built for short, styled cruising and making a visual statement rather than covering distance or chasing performance.
Rider Fit	The low seat height and light weight make it very manageable for shorter or less physically confident riders.
Character	It has laid-back bobber attitude, with a hardtail-look rear end, chunky tyres, and a solo seat that prioritize looks over outright capability.
Not Ideal For	This bike is not for riders wanting highway touring, passenger comfort, or any kind of spirited, high-speed riding.

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

Feet:

At 640mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 AJS Bobber 125, with a cramped knee angle of around 70 degrees and an upright 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.
