Rider Profile

Best ForThis is a machine for seasoned, confident riders who understand how to manage massive low-end torque from a car-derived V8 in a two-wheeled chassis.
PurposeBuilt as a straight-line power statement and drag-strip curiosity rather than a corner-carving sportbike, despite its Sport category label.
Rider FitIts long wheelbase, heavy dry weight, and low seat height demand strength and deliberate inputs at low speed, though the stance is stable once rolling.
CharacterA brash, spectacle-driven muscle bike that trades agility and refinement for raw, thunderous V8 acceleration and show-stopping presence.
Not Ideal ForThis is not the right choice for new riders, tight urban commuting, off-road use, or anyone wanting nimble, flickable cornering manners.

2010 Cosmos Muscle Bikes 4RWF V8 Rider Ergonomics Assessment

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

Feet:

At 700mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Cosmos Muscle Bikes 4RWF V8, with a cramped knee angle of around 60 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.
