Rider Profile

Best ForThis bike suits intermediate to experienced riders comfortable with a torquey V-twin and a firm sporty chassis.
PurposeIt's built primarily for spirited backroad riding and light sport-touring rather than outright racetrack dominance or long-haul touring.
Rider FitThe 831mm seat height and 204kg dry weight demand a rider of average-to-above-average height and reasonable strength for slow-speed maneuvers.
CharacterIt has the personality of a raw, characterful V-twin sportbike, delivering strong midrange torque and eager handling from its lightweight trellis-style chassis and inverted forks.
Not Ideal ForIt's not a good fit for beginners, taller touring riders needing wind protection, or anyone seeking off-road capability.

2015 ATK GT650R Rider Ergonomics Assessment

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

Feet:

At 831mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2015 ATK GT650R, with a cramped knee angle of around 75 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.
