Best ForIdeal for beginners, learners, or anyone needing a simple, low-risk moped-class scooter for basic mobility.
PurposeBuilt purely for short urban hops, errands, and commuting at low speeds rather than any kind of performance riding.
Rider FitIts low seat height, light 95 kg weight, and automatic transmission make it extremely easy and unintimidating for riders of almost any size or strength.
CharacterA practical, economical, and unassuming little runabout that prioritizes efficiency and ease of use over excitement.
Not Ideal ForNot suitable for highway travel, touring, carrying a passenger comfortably, or any rider seeking speed or off-road capability.

2017 Yamaha Neos 4 Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2017 Yamaha Neos 4, 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.
