This specification indicates the configuration of the mounting points on an all-terrain vehicle’s wheel hub, defining how the wheel attaches to the vehicle. It is expressed as the number of bolt holes and the diameter of the circle they form. For instance, a “4/115” designation signifies four bolts positioned on a circle with a 115mm diameter. This dimension is critical for ensuring proper wheel fitment.
Correct wheel attachment is essential for vehicle safety and performance. Using wheels with the incorrect measurements can lead to wheel detachment, damage to the hub, and potential accidents. Its standardization simplifies wheel selection and ensures compatibility across different ATV models and aftermarket options. Historically, variations existed, making wheel swaps challenging; standardization streamlines this process, benefiting both owners and mechanics.
