The configuration of studs or holes used to attach a wheel to the hub of a Yamaha all-terrain vehicle (ATV) is defined by a specific measurement. This measurement, often expressed as a numerical ratio, indicates the number of studs and the diameter of the circle they form. For example, a 4/110 designation signifies four studs arranged on a circle with a diameter of 110 millimeters. This specification is crucial for ensuring compatibility between the ATV and aftermarket wheels or replacement parts.
Precise wheel fitment is paramount for safe and optimal ATV operation. Using an incorrect wheel mounting configuration can lead to wheel instability, potentially causing damage to the vehicle’s hub, axle, or wheel itself. Historically, manufacturers have utilized distinct configurations across various ATV models and production years. Understanding the correct wheel mounting specification prevents mechanical failures, maintains vehicle handling characteristics as designed by the manufacturer, and contributes to the overall safety and longevity of the ATV.
