Rider Profile

Best ForThis 50cc automatic scooter is ideal for absolute beginners or those wanting simple, low-stakes transportation with minimal learning curve.
PurposeBuilt purely for short-hop urban commuting and running errands, not for speed or distance.
Rider FitIts very light weight and low seat height make it accessible to riders of nearly any size or strength, including smaller or less confident riders.
CharacterA practical, unpretentious little runabout that prioritizes ease of use and maneuverability over performance or excitement.
Not Ideal ForThis is not for riders seeking highway speeds, long-distance touring, or any kind of sporty or off-road performance.

2009 Yamaha Slider Naked Rider Ergonomics Assessment

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

Feet:

At 787mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Yamaha Slider Naked, with a moderate knee angle of around 95 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.
