REAR WHEEL SPACER KIT KTM 250 SX 2013-2016 MX POSITIVO MXRSR20166 ALLUMINIO

The spacers wheel fitted as standard on modern off-road motorcycles, if they are made of aluminum, highlight notoriously accelerated wear at the contact point with the oil seal lip. The groove that is formed at that point nullifies the action of the oil seal, resulting in the accelerated wear of the bearings, due to infiltration of water and earth. The ProX wheel spacers have been designed to overcome this problem and the result obtained allows to have the strength of steel but with the weight of the aluminum! Indeed, such spacers are made of aluminum, with black hard anodizing, and encapsulated for pressing with a steel shell, positioned in the point of contact with the lip of the oil seal. Where the wheel spacers mounted series are made of steel and with a thickness such as not to allow the aluminum construction, even the ProX wheel spacers are constructed entirely of steel. The ProX wheel spacers are appropriate, comprehensive and permanent solution to the problem of sealing the wheel bearings, while also allowing a long life and excellent smoothness.
