The highest quality rear drive for karting comes from X-Treme. Made from the hardest aluminium alloy. The teeth are cut with precision and the angles of the teeth are designed to provide the lowest possible friction. The chain runs well around the sprocket to minimise friction.
Unique design of the drive to save weight as it rotates while the hard alloy allows the gear to keep its shape.
Black anodised with laser engraved size indication. For those who want to hide which great is on the kart, this marking can be used to turn the sprocket inwards so it is not visible to the nosy competitor.
