Rider Profile

Best ForThis is a beginner-friendly small-displacement machine, well suited to new riders building confidence.
PurposeIt is designed as a low-cost, low-power cruiser-styled commuter for casual around-town use rather than performance riding.
Rider FitThe unusual chopper-style setup with a 21-inch front and 16-inch rear wheel combined with a low 640mm seat height and light 114kg weight makes it accessible to riders of most sizes and confidence levels.
CharacterIt has a quirky cruiser-inspired look with mismatched wheel sizes, giving it a novelty custom-bike character despite its modest small-engine underpinnings.
Not Ideal ForThis is not the bike for riders seeking real speed, long-distance touring comfort, or serious off-road capability.

2009 AJS Regal-Raptor EOS-125 Rider Ergonomics Assessment

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 2009 AJS Regal-Raptor EOS-125, 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.
