Rider Profile

Best ForIdeal for beginners and commuters; twist-and-go automatic makes it approachable, while enough poke for confident riders in traffic.
PurposeBuilt for urban commuting and errands. Large 16-inch wheels handle rough city streets, and it can hold its own on faster roads and short highway hops.
Rider FitLight 169kg, low 805mm seat and step-through layout suit most riders. Upright, relaxed ergonomics with weather protection and easy footing at stops.
CharacterA practical, refined premium scooter. Smooth liquid-cooled single, automatic CVT, ABS and LED lights make it a fuss-free, dependable daily companion.
Not Ideal ForNot for track days, off-road, long two-up touring or riders wanting big-bike power, luggage capacity or high-speed cruising.

2018 Honda SH300I Rider Ergonomics Assessment

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

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Honda SH300I, with a moderate knee angle of around 105 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.
