Parts Unlimited Standard Inner Tube - 4.00-8 - JS244A

Upgrade your ride with the PARTS UNLIMITED 8" motorcycle inner tube, engineered for superior air retention and lasting performance.

Description

Experience unparalleled reliability on the road or trail with the PARTS UNLIMITED Standard Inner Tube. Specifically designed for motorcycles, this durable tube is suitable for both front and rear applications on an 8" rim, fitting tire sizes 4.00-8 perfectly. Its 100% butyl polymer construction significantly minimizes natural air leakage, a common issue with blended rubber tubes, providing consistent air pressure and a more stable ride. With a robust 2.0 mm tube thickness, it offers excellent puncture resistance for everyday riding. The integrated center metal valve features a convenient 90-degree bend (JS-244A type), making inflation and pressure checks easier, especially in tight spaces. Each butyl inner tube is individually boxed and clearly marked, simplifying selection and storage for mechanics and enthusiasts alike.
