This replacement tube helps restore dependable air retention and supports proper tire performance for compatible motorcycle applications. Built by Bridgestone, it is a practical choice for replacing a worn, punctured, or aging inner tube during routine tire service or repair.\u003cbr\u003eThe Standard tube is manufactured for use with compatible tube-type motorcycle tires and should be matched carefully to the tire size, rim configuration, and valve stem requirement specified by the vehicle or tire manufacturer. The 140\/150\/90-15 size designation identifies the intended tire fitment, while the PV78 valve stem provides the required inflation connection for compatible wheel assemblies. Always inspect the tire and rim before installation to confirm there are no sharp objects, corrosion, damage, or other conditions that could affect the new tube.\u003cbr\u003eFor reliable installation, use appropriate tire service tools and avoid pinching, twisting, or overstretching the tube. Inflate gradually and verify that the tube is seated correctly inside the tire before completing installation. The Bridgestone Standard motorcycle inner tube is identified by manufacturer part number 548588 and vendor part number 548588, providing a clear reference for ordering and replacement documentation. It is supplied as a replacement inner tube and is intended for applications that specifically call for the 140\/150\/90-15 fitment with a PV78 valve stem.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBridgestone Standard motorcycle inner tube for compatible tube-type tire applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for the 140\/150\/90-15 tire size\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEquipped with a PV78 valve stem\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufacturer part number: 548588\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVendor part number: 548588\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for replacing worn, punctured, or aging inner tubes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUse with compatible motorcycle tires and wheel assemblies\u003c\/li\u003e\u003c\/ul\u003e","brand":"BRIDGESTONE","offers":[{"title":"Default Title","offer_id":49388195348715,"sku":"874-1914","price":32.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/7e15-68813371ea597_2c18b311-731a-4115-99be-c243dea5bf84.png?v=1789023485","url":"https:\/\/ctracingservices.com\/products\/bridgestone-standard-motorcycle-inner-tube-140-150-90-15-pv78-valve-stem-part-number-548588","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
