Rider Profile

Best ForBest suited to riders who already have experience with big, heavy custom cruisers, given the massive 260mm rear tire and long, low-slung chassis.
PurposeBuilt as a boulevard and show-cruiser statement bike, prioritizing style, torque, and presence over outright speed or agility.
Rider FitThe low 610mm seat height makes it accessible for shorter riders, but the 272kg dry weight demands confident low-speed handling and upper-body strength at a standstill.
CharacterA big-inch air-cooled V-twin custom with a wide rear tire, chopper-ish rake, and premium suspension components that signal a boutique, hand-built cruiser character.
Not Ideal ForNot a fit for riders wanting sharp cornering, off-road capability, or a lightweight, nimble city commuter.

2009 Viper Diablo Rider Ergonomics Assessment

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

Feet:

At 610mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2009 Viper Diablo, with a cramped knee angle of around 65 degrees and an upright riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
