Rider Profile

Best ForThis is a machine for confident, experienced riders who are comfortable managing a massive, heavy, three-wheeled vehicle with car-like power delivery rather than typical motorcycle handling.
PurposeBuilt as a novelty muscle-trike spectacle, it exists to deliver explosive straight-line acceleration and jaw-dropping presence rather than sporty handling or practicality.
Rider FitRiders need decent upper body strength and confidence at low speed to manage its immense weight and width, though the automatic transmission and trike stability remove clutch and balance concerns.
CharacterA brash, V8-powered showpiece for riders who want outrageous torque, deep exhaust rumble, and maximum attention wherever they go.
Not Ideal ForThis is not for riders seeking agility, cornering finesse, off-road capability, or a lightweight, nimble ride.

2011 Boss Hoss BHC-9 ZZ4 Trike Rider Ergonomics Assessment

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

Feet:

At 737mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Boss Hoss BHC-9 ZZ4 Trike, with a cramped knee angle of around 85 degrees and a slightly forward 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.
