Rider Profile

Best ForBest suited to riders who already have experience with heavy, long, low-slung custom cruisers and their unique low-speed handling demands.
PurposeBuilt primarily as a bold, head-turning boulevard cruiser for style-focused riding rather than outright performance.
Rider FitThe extreme 40-degree rake, long 88-inch wheelbase, and 317.5 kg dry weight make this a physically demanding machine to muscle around at parking-lot speeds despite its low 508mm seat.
CharacterA brash, chrome-and-torque American V-twin chopper that rewards relaxed, straight-line cruising with a deep, punchy powerplant and a dramatic stretched-out stance.
Not Ideal ForNot for riders seeking nimble cornering, off-road capability, or a lightweight, flickable ride.

2009 Big Bear Choppers Athena 100 EFI Rider Ergonomics Assessment

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

Feet:

At 508mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Big Bear Choppers Athena 100 EFI, with a cramped knee angle of around 60 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.
