Rider Profile

Best ForThis is best suited to riders who already have some experience with heavy, torque-driven V-twin cruisers and low-speed weight management.
PurposeBuilt primarily for relaxed boulevard cruising and image-driven custom styling rather than outright speed or cornering agility.
Rider FitThe low 635mm seat height helps shorter riders reach the ground, but the substantial dry weight of over 260kg demands confident low-speed handling and upper body strength at a stop.
CharacterIt has the classic big-inch V-twin custom cruiser persona: a low, long, laid-back stance with a thumping engine character and straightforward mechanical feel over refined electronics.
Not Ideal ForThis is not the right bike for riders seeking sharp cornering performance, off-road capability, or a lightweight, flickable ride.

2006 Ridley X88 Rider Ergonomics Assessment

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

Feet:

At 635mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 Ridley X88, with a cramped knee angle of around 70 degrees and an upright 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.
