Type / Use: Motorcycle inner tube, designed for use inside the tire to hold air.
Valve Type: TR6 (center metal valve stem) — robust and typical for heavy or thick tubes.
Size / Fit Range: The example tube is 325/350-19; your spec “300/325 × 19” is a bit narrower, but the tube design is comparable.
Material & Construction: Seamless rubber construction, heavy duty or ultra heavy duty grades.
Applications / Notes: Used in offroad, vintage, or standard motorcycles with 19-inch wheels. Tubes often need correct matching with tire width and rim.
Limitations / Caveats: Must ensure the tube’s cross section matches your tire (300/325) — using a too wide or too narrow tube can cause premature wear or failure.
