Reinforced off-road motorcycle inner tube from Michelin, built around their well-known Airstop butyl compound for improved air retention. Wall thickness is set above road-tube standards from the start, which is why Michelin's "standard" tube is already a proper off-road tube and not a light road item. Suitable for trail riding, adventure touring, green laning, and dual-sport use at typical off-road pressures. The right pick when you want a quality Michelin tube without paying for the extra weight of heavy duty or ultra heavy duty options. Available in sizes matched to common front and rear off-road and adventure tyre fitments.
