Best for: Built as a bold American custom cruiser, it's meant for making a statement on boulevards and at bike nights rather than for outright performance or long-distance touring efficiency.
Built for: Torque-rich 45-degree V-twin with a big-inch feel, chrome-heavy custom styling, an aggressive raked-out stance, and a boutique feel courtesy of the Baker overdrive transmission and premium Marzocchi suspension.
Not ideal for: This is not the right choice for riders seeking agile cornering, off-road capability, or a lightweight commuter, as its stretched geometry and heavy mass make tight, technical riding cumbersome.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

Inseam (optional)

Units

At 610mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2015 Viper Diamondback, with a cramped knee angle of around 70 degrees and an upright riding position.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
