Detailed Product Information
A motorcycle inner tube sits inside a tube-type tyre and contains the air pressure that supports the tyre and motorcycle. Correct sizing matters: the tube must match the tyre width and rim diameter closely enough to sit inside the tyre without excessive stretching, folding or pinching. This 2.75-18 size is intended for compatible 18-inch motorcycle wheels using a 2.75-section tube-type tyre.
The directly cross-referenced CMPO INT031 tube is specified with a centre rubber valve and is also described by CMPO as suitable for some wheels/tyres that use a 2.50-18 tube. Michelin's 18ME TR4 is a separate branded size-equivalent reference covering 2.75-18 and other nearby 18-inch tyre sizes. These references are included to help buyers compare size and specification; this MotoMania item is sold as an unbranded aftermarket tube.

Important Fitment Checks
- Read the tyre sidewall and confirm the required size before ordering.
- Confirm the wheel is designed to use an inner tube; some later replacement rims or tyres may be tubeless.
- Compare the valve position and valve style with the existing tube and rim hole.
- Check the rim tape for damage and remove sharp debris from inside the tyre before installation.
- Model-year data is a guide. Tyres, rims and wheel assemblies may have been changed during the motorcycle's life.
Installation Advice
Fitment should be carried out carefully to avoid trapping or pinching the tube between the tyre bead and rim. Add a small amount of air before final bead seating so the tube takes its natural shape. After fitting, inflate to the motorcycle or tyre manufacturer's recommended pressure and recheck that the tyre bead is evenly seated.
