  • ✅ MADE FROM HIGH QUALITY PREMIUM MATERIALS - ProTrax super thick inner tube is a blend of natural and butyl rubber. Butyl rubber is the perfect choice because it's great for shock absorption and has exceptionally resistant to heat, aging, puncture, and weather. The rubber is twice as thick as OEM tubes to help resist punctures and pinch flats. These inner tire tubes are designed to last and keep you riding longer!
  • ✅ MAXIMIZE YOUR PERFORMANCE - Finally a tire tube you can rely on! All levels of riders covered, from the amateur racers reaching for pro status, to the weekend trail rider who is just out having fun with his kids. No matter if you are riding on the highway or driving over rocks, tree stumps, gravel, or ditches, our ProTrax tubes were built with reliability and safety in mind.
  • ✅ ADVANCED TECHNOLOGY AND STRONG FABRICATION PROVIDES MORE SAFETY - These tubes are designed to hold the valve stem powerfully to the tube. Unlike lower quality OEM tubes, ProTrax inner tire tubes are less likely to pinch when changing. Every inch of these tubes is made using the finest materials and advanced technology, considering the endurance and performance expected. Using ProTrax tire inner tubes will decrease your chances of getting a flat tire compared to competing tubes on the market
  • ✅ OPTIMAL THICKNESS AND COMPATIBILITY - These tire tubes measure 3mm thick, and fits 2.75-3.00 x 21 inch front tires (2.75-21, 3.00-21, 90/90-21, 70/100-21, 80/100-21, 100/80-21). We know other brands offer 4mm tubes, but from our experience, they are too stiff, not flexible, and limits the motor cycle. Compatible with various Honda, Husaberg, Husqvarna, Kawasaki, KTM, Suzuki, and Yamaha dirt bike models. Please refer to fitment chart before purchasing to confirm this product will fit.
