Bridgestone Radial Tire Tube – 120/70-17 & 150/70-17 | Inner Tube for Spoked Wheel Radial Tires

The Bridgestone Radial Tire Tube is purpose-built for motorcycles that run tube-type radial tires on spoked wheels — a common setup on retro, scrambler, and classic-style bikes where tubeless rims aren’t an option. Available in two sizes to cover the most popular front and rear fitments: 120/70-17 and 150/70-17.

Engineered by Bridgestone to pair correctly with radial tire construction, this tube maintains proper seating and pressure integrity under the higher stress loads that radial tires generate compared to bias-ply tires. A direct, reliable replacement when you need to re-tube or repair a spoked wheel radial setup.
