Rider Profile

Best ForThis is a friendly, low-intimidation bike well suited to beginners and casual riders who want simple, easygoing fun rather than outright performance.
PurposeIt's built as a light, flat-track styled all-rounder for cruising around town and occasional light dirt-road or trail exploring rather than for speed or long-distance touring.
Rider FitThe low 790mm seat height and light 139kg dry weight make it very approachable for shorter or less experienced riders to handle and manage at low speeds.
CharacterIt has a laid-back, retro flat-tracker personality with modest single-cylinder power delivered smoothly, favoring easy manageability over aggression.
Not Ideal ForThis bike is not for riders seeking highway speed, long-haul touring comfort, or serious off-road capability.

2002 Suzuki Grasstracker BigBoy 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 2002 Suzuki Grasstracker BigBoy, with a relaxed knee angle of around 120 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.
