It perfectly accommodates popular tire sizes including 110/90-19, 120/80-19, 4.00-19, and 4.50-19, making it a versatile component for many motorcycles. Each inner tube is individually boxed, featuring clear markings for size and valve stem type (TR-4 Round Base, Center Metal Valve with Threaded Nuts), simplifying selection and storage for mechanics and riders alike.
