This 16-inch heavy-duty inner tube by Zodiac is engineered from butyl rubber to provide exceptional air retention. Because butyl is less porous than natural rubber, it maintains internal pressure more effectively over time, which is critical for the safety and performance of tubed motorcycle tires. This tube is designed to handle the weight and torque of large cruisers, offering a robust solution for riders who require a dependable tube for their 16-inch wheels. It is a fundamental component for any workshop servicing classic or modern Harley-Davidson motorcycles.
