PARTS UNLIMITED Inner Tube - Standard - 16" - TR-4 B20035

Air retention is critical when you're running consistent lap times or depend on your bike for daily reliability. The PARTS UNLIMITED Inner Tube uses 100% butyl polymer—not a blended compound—which means significantly less natural air leakage compared to standard tubes. This delivers stable tire pressure over extended periods, reducing the need for constant top-offs and ensuring your handling characteristics remain predictable when it matters most.

Built to straightforward specifications with clear valve stem and size markings on every box, this tube installs as a direct replacement and performs without compromise. Whether you're prepping for track day or maintaining consistent pressure on the street, real butyl construction keeps your tires pressure-stable so you can focus on riding.
