Rider Profile

Best ForBest suited to intermediate to experienced off-road riders comfortable with a tall, light, aggressive enduro machine.
PurposeBuilt purely for technical enduro and off-road riding, not for street commuting or highway travel.
Rider FitThe tall 900mm seat height and minimal seat padding demand good leg length and fitness, though the very light dry weight around 109kg makes it easy to muscle around at low speed or when picking it up.
CharacterA raw, purpose-built enduro weapon with a light, torquey four-stroke single, long-travel suspension, and razor-sharp agility for tight trails and technical terrain.
Not Ideal ForNot a good fit for riders wanting a comfortable daily commuter, a passenger-friendly bike, or sustained high-speed road touring.

2006 Sherco 4.5i Enduro Rider Ergonomics Assessment

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

Feet:

At 900mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2006 Sherco 4.5i Enduro, with a cramped knee angle of around 80 degrees and an upright 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.
