12" Heavy Duty Bent Valve Scooter Inner Tube

12-Inch Heavy Duty Bent Valve Inner Tube for Scooters and Mini-Motos

This 12-inch inner tube is made to keep a scooter, mini-moto, or sidecar running easily. It is molded from dense butyl rubber, which resists seam splits and pinch flats. Among scooter inner tubes, it is intended to handle sustained loads and high internal heat, so it suits a range of uses.

Construction and Design

The tube has an even wall thickness and good flexibility, which helps limit air loss over time. Its 90° bent metal valve stem makes inflating easier, including in narrow wheel hubs. A reinforced valve base also helps it hold up by absorbing twisting force and guarding against pull-shear flats.

Installation and Maintenance

Before fitting the new tube, look inside the tire casing for sharp objects or debris. To lower the chance of pinch flats, dust the inside of the tire with talcum powder before inserting the tube. Careful inspection and preparation make the installation go more smoothly.
