Product Details
✓UNIVERSAL FIT 2.25/2.50-16” OFF-ROAD MOTORCYCLE INNER TUBES - These inner tubes fit motorcycle tires with an inner diameter (rim diameter) of 16 inches, an outer diameter of 21 inches, and widths that are between 2.25 inches to 2.50 inches. It has the same dimensions and specifications as the 70/90-16, 80/80-16, 80/90-16, and 90/80-16 motorcycle tires, and 2.50-16 dirt bike tubes.
✓COMPATIBLE REPLACEMENT INNER TUBES FOR DIRT BIKES, PIT BIKES, AND OFF-ROAD MOTORCYCLE - Several brands and models that are compatible with this size of inner tubes include Honda CRF 80F (front tire), Honda XR 80/XR 80R (front tire), and most motorcycles with standard tires.
✓TR4 STRAIGHT VALVE STEM FOR HIGH TORQUE APPLICATIONS - Centered with a straight and round stem, the TR4 valve fits most rims with a round valve base. Designed specifically for relatively low psi motorcycle and ATV/UTV tires. As they are secured to the rim with nuts and washers, there is a lesser risk of the valve disappearing down to the rim when pumping air.
✓ENJOY OPTIMUM RIDING COMFORT - Made from natural rubber and butyl blend, these inner tubes have a superior impact and vibration dampening property. And as they are also thicker than average inner tubes in the market, the dampening effect doubles, enabling the inner tubes to work effectively in tandem with the bike’s suspension system to provide you with the most comfortable ride.
✓IMPORTANT NOTE: This replacement kit is an aftermarket product produced by CalPalmy (TM). It meets or exceeds the performance of OEM replacements (based on in-house testing). We do not have any affiliation with or endorsement from any of the manufacturers mentioned.
