Sur-Ron Ultra Bee 19-Inch Inner Tube

19-Inch Inner Tube for the Ultra Bee

This replacement inner tube is for the Sur-Ron Ultra Bee wheel setup using a compatible 19-inch tire. It can be used at the front or rear 19-inch wheel position when the tire and rim specifications match.

Confirm the Tire and Rim Size

Read the size marking on the tire sidewall and compare it with the current tube before ordering. Check the rim diameter, tire width range, valve type, valve position, and rim condition. A 19-inch rim diameter alone is not enough if the tire width or valve arrangement differs. Inspect the tire for embedded objects, damaged bead areas, cuts, and worn tread before fitting a new tube.

Installation and Inflation

Use tire tools carefully so the new tube is not pinched between the tire bead and rim. Add a small amount of air before seating the tire, confirm that the tube is not twisted, and check that the valve sits straight. Inflate gradually to the pressure specified for the motorcycle and tire combination. After installation, inspect both bead lines, verify stable pressure, and recheck the valve and tire before riding. Replace damaged rim tape or correct sharp rim edges before installing the tube.
