Rider Profile

Best ForIdeal for beginners, new licence holders, and younger riders taking their first steps into sportbike styling and handling.
PurposeBuilt for learner-legal commuting and urban sport riding rather than outright performance, wrapped in genuine GSX-R race-replica styling.
Rider FitIts light weight and low seat height make it very manageable for smaller or less experienced riders, with minimal effort needed at low speed or in stop-and-go traffic.
CharacterA playful, nimble little sportbike that rewards revving the small single hard and flicking it through corners rather than chasing top speed.
Not Ideal ForNot suited to riders wanting real highway overtaking power, long-distance touring comfort, or two-up riding.

2018 Suzuki GSX-R125 GP Rider Ergonomics Assessment

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

Feet:

At 785mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Suzuki GSX-R125 GP, with a cramped knee angle of around 70 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.
