3.00-18 Inner Tube for Yamaha YB100 / RXS100
Replacement 3.00-18 motorcycle inner tube for compatible 18-inch motorcycle wheels. This listing has been revised to avoid broad model claims where the original tyre or wheel specification does not match the tube size.

Fitment note: Generic YBR125 fitment was removed. Standard YBR125 tyre specifications vary by model/market and are not a clean 3.00-18 vehicle-wide application.
Important Compatibility Check
Read the tyre sidewall before ordering and confirm the required inner-tube size. Also compare the valve position and valve style with the existing tube and rim hole. Motorcycle wheels and tyres are often changed during a vehicle's life, so model and year data should not override the size marked on the tyre or the wheel manufacturer's requirements.
Tubeless warning: Do not assume an inner tube is required simply because the motorcycle uses an 18-inch tyre. Some listed or related models were originally supplied with tubeless tyres. If the fitted wheel is tubeless, follow the tyre and wheel manufacturer's instructions rather than fitting a tube by default.
Installation Advice
Inspect the tyre interior and rim tape before fitting. Remove sharp debris, lightly inflate the tube before final bead seating, and make sure the tube is not trapped between the tyre bead and rim. Inflate to the motorcycle or tyre manufacturer's recommended pressure after installation.
