This part being universal, it may require adaptations
RFX MT609-OT338.4MM Inner Tube — designed for 18-inch wheels, this Ultra Reinforced inner tube is aimed at demanding riders who want a durable and reliable part for their 3.25/3.50-18 or 90/90-18 tires. Manufactured by RFX, it combines robust materials and careful finishing to minimize the risk of abrasion on the sides and friction against the rim.
Designed for both road and light off-road use, this RFX inner tube is easy to install and handle during workshop interventions or roadside repairs. Its reinforced profile offers better performance against daily stresses (contacts with the rim, internal friction) while remaining compatible with most 18" rims. Essential in a rider's toolkit, it allows for a quick return to riding in case of a flat tire or during a tire change.
