Rider Profile

Best ForThis bike suits riders with at least some prior experience who want a lively, high-revving four-cylinder sportbike feel without the intimidation of a larger machine.
PurposeIt's built primarily for spirited sport riding and enjoyable back-road carving in a compact, mid-displacement package.
Rider FitThe low seat height and light overall class make it accessible to shorter or smaller riders, though the sporty riding position still puts moderate weight on the wrists.
CharacterExpect a smooth, free-spinning in-line four with a sporty, eager character typical of Japanese 400cc four-cylinder machines from this era.
Not Ideal ForIt's not the right choice for riders seeking long-distance touring comfort, passenger-friendly ergonomics, or any off-road capability.

2005 Suzuki GSX 400 Impulse 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 2005 Suzuki GSX 400 Impulse, with a cramped knee angle of around 65 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
