Rider Profile

Best ForThis big-inch American V-twin custom suits riders who already have experience handling heavy, low-slung cruisers with long wheelbases and raked-out front ends.
PurposeBuilt as a boulevard-style custom cruiser, it's meant for style-focused low-speed cruising and show-worthy presence rather than performance riding.
Rider FitThe low 616mm seat height makes it easy to get feet down, but the substantial 324kg wet weight demands real strength and confidence at parking-lot speeds and in tight maneuvers.
CharacterIt has a raw, torquey, air-cooled big-twin character with a distinctive fat rear tyre stance and chopper-inspired 39-degree rake that broadcasts custom-culture attitude over outright capability.
Not Ideal ForIt's not for riders wanting agile cornering, off-road versatility, sporty acceleration, or long-distance touring comfort with wind protection and storage.

2008 Big Dog Ridgeback Rider Ergonomics Assessment

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

Feet:

At 616mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 Big Dog Ridgeback, with a cramped knee angle of around 70 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.
