Twin Power Tube 325/350-19 TR6 Metal Center Valve

This is a heavy-duty inner tube from TwinPower, sized for 325/350-19 tires. It features a TR6 metal center valve stem, which is a common type for many motorcycle applications. If you're working on a popular American V-Twin or a custom build that uses this tire size, this tube is a solid option.

It's made from seamless, natural rubber, which is a well-built material for inner tubes. This construction helps ensure it holds air reliably. The valve stem is also heavy-duty, meaning it's built to last and resist damage during installation or regular use. This tube is designed to fit right into the specified tire sizes, making installation straightforward.
