Rider Profile

Best ForThis is a beginner-friendly small-displacement machine, well suited to new riders or those wanting a low-stress learner bike.
PurposeIt's built as a simple, light commuter and runabout for short trips rather than a bike for performance or long-distance travel.
Rider FitThe low 770mm seat height and light 106kg dry weight make it accessible to riders of most sizes and confidence levels.
CharacterIt has an easygoing, classic-styled retro-roadster character with modest carbureted single-cylinder charm rather than outright excitement.
Not Ideal ForIt's not the right choice for riders wanting highway speed, extended touring comfort, or any serious off-road capability.

2017 WK RT 125 Rider Ergonomics Assessment

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

Feet:

At 770mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2017 WK RT 125, with a moderate knee angle of around 110 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.
