Oplite NitroKart Universal Seat Reducer USR

Oplite NitroKart Universal Seat Reducer USR The NitroKart Universal Seat Reducer (USR) is a high-density elastomer seat insert that drops straight into M/L and XL/XXL karting bucket seats, giving smaller drivers proper lateral support. It installs by simple insertion, with no tools and no modification, and works both on a sim racing cockpit and in a real kart — which makes it just as relevant for private owners as for karting circuits and driving schools.

Usable in a real kart: a practical solution for karting circuits, driving schools and private owners alike. Non-slip, moisture-resistant surface, built for repeated use.

For children and smaller drivers who lack lateral support in a full-size karting bucket seat. By reducing the internal volume of the seat, the insert holds the driver properly in place — which improves both comfort and control. Does it fit my seat? It is designed for karting bucket seats in size M/L and XL/XXL, including those of the NitroKart V1 and V2 cockpits and real karting seats. If you are unsure about your seat, contact us with its model and size and we will check it for you. Is installation complicated? No. The insert simply drops into the seat, with no tools, no fixings and no modification. It comes out just as easily when an adult driver takes over. Can I use it in a real kart? Yes. It is designed for both sim racing and real karting use, which makes it a practical solution for karting circuits and driving schools running mixed-age sessions, as well as for private owners. How do I clean it? With soapy water. The elastomer is moisture-resistant and its non-slip surface is designed for repeated use, which matters in a rental or club environment. Video
