Rider Profile

Best ForSuitable for absolute beginners and learner-permit riders, including those with no prior motorcycle or scooter experience.
PurposeDesigned purely for short, low-speed urban errands and commuting at moped-legal speeds rather than any performance riding.
Rider FitVery light and low, so it demands minimal strength or balance, making it accessible to smaller or less confident riders.
CharacterA simple, unintimidating twist-and-go 50cc-class runabout focused on cheap, easy, no-fuss city mobility.
Not Ideal ForNot suitable for highway riding, touring, carrying a passenger comfortably, or anyone wanting real acceleration or power.

2009 AJS Exactly 50 Rider Ergonomics Assessment

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

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 AJS Exactly 50, with a moderate knee angle of around 100 degrees and a slightly forward 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.
