Rider Profile

Best ForThis is a friendly, low-intimidation machine best suited to new riders or those upgrading from a smaller learner bike.
PurposeIt's built as an affordable, light-duty naked bike for commuting and everyday urban riding rather than performance or distance work.
Rider FitThe low seat height and light dry weight make it easy for shorter or less experienced riders to handle at a stop or in traffic.
CharacterIt has an approachable, unintimidating single-cylinder character with modest power delivered in a simple, air-cooled package.
Not Ideal ForIt's not the right choice for riders wanting serious motorway speed, long-distance touring comfort, or off-road capability.

2016 AJS TN25 250 Rider Ergonomics Assessment

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2016 AJS TN25 250, 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.
