Motorcycle Tubes, Valves and Repaired Tyres
Ensure that the correct size and type is fitted and that the valve stem tightly fits the hole in the rim. Always use a new tube when fitting a replacement tube-type tyre. Tubes that are stretched, thinned or excessively repaired may deflate without warning and should not be re-fitted.
Tubes must always be used with tyres fitted to wire-spoked wheels, except for those wire-spoked rims specifically designed for tubeless tyres. A rim band or a rim tape of the correct type must be fitted to protect the tube from spoke head damage.
Inner tubes of the correct size may only be used with tubeless tyres if correctly fitted and approved by the individual tyre manufacturer. It must, however, be emphasised that the result of fitting tubes in tubeless tyres is that, in the event of a puncture, the assembly will behave in exactly the same way as a tube-type tyre and tube assembly, i.e. it is likely to lose pressure more rapidly than a tubeless tyre assembly.
Tyres that are marked ‘Tube Type’ or are not marked ‘Tubeless’ must be fitted with an inner tube.
