About the OTK MXC Wheel

The MXC is manufactured using a forged magnesium process, which produces a denser, more rigid wheel than cast alternatives. Its rigidity helps dissipate tyre heat more quickly, which supports consistent tyre pressures and grip levels over longer race runs. The MXC is particularly well suited to high-grip track conditions or warmer ambient temperatures, where keeping the tyre cool and maintaining setup stability are key. It is the wheel most commonly used in competitive OK and KZ racing where grip levels are high.

Wheel hub compatibility is specific to the OTK standard M8 stud pattern. Confirm hub and stud fitment on your chassis before ordering. Compatible with the OTK rear hub range and paired with the OTK K Nut and wheel studs.
