Rider Profile

Best ForThis is an entry-level commuter bike best suited to new riders or those with a learner license.
PurposeIt is designed primarily for short urban commutes and light city riding rather than performance or long distance use.
Rider FitThe low seat height and light dry weight make it easy to manage for riders of most sizes and modest strength.
CharacterIt has a mild-mannered, low-revving single-cylinder character with modest power delivery suited to relaxed, low-speed riding.
Not Ideal ForIt is not suitable for riders seeking highway touring, high speed performance, or off-road capability.

2013 Keeway RKS 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 2013 Keeway RKS 125, with a moderate knee angle of around 110 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.
