Rider Profile

Best ForThis bike suits newer to intermediate riders looking for a manageable, revvy naked/allround machine rather than a beginner's first-ever motorcycle.
PurposeIt's designed as a light, nimble all-rounder for spirited city riding and twisty backroads rather than outright speed or long-distance cruising.
Rider FitThe low 760mm seat height and light 177kg dry weight make it accessible to shorter or lighter riders with minimal physical strain.
CharacterIt has the personality of a peppy, high-revving inline-four that rewards spinning it up through the gears for its performance rather than relying on low-end torque.
Not Ideal ForIt's not a good fit for riders wanting serious highway touring comfort, passenger-friendly ergonomics, or any off-road capability.

2011 Suzuki Impulse 400 Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Suzuki Impulse 400, with a moderate knee angle of around 115 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.
