Rider Profile

Best ForThis is an ideal machine for absolute beginners or anyone who just needs simple, low-stakes transportation.
PurposeBuilt purely for short-hop urban commuting, running errands, and weaving through congested city streets.
Rider FitIts tiny size, low seat height, and featherweight 84kg build make it accessible and unintimidating for riders of almost any stature.
CharacterA cheerful, no-fuss economy scooter that prioritizes fuel efficiency and easy handling over any kind of performance.
Not Ideal ForThis is not the machine for highway travel, carrying a passenger any real distance, or anyone seeking speed or excitement.

2012 Yamaha Jog Rider Ergonomics Assessment

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

Feet:

At 710mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Yamaha Jog, with a cramped knee angle of around 85 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.
