Got a flat on your pit bike or small dirt bike? These HIAORS inner tubes are a reliable replacement. You get two tubes in size 3.00-12 (also fits 80/100-12 tires), with straight valves that work with most standard rim holes. They’re made from heavy-duty rubber to resist punctures and hold air well. Compatible with many 12-inch wheel bikes like Honda XR/CRF50/70, Kawasaki KLX110, Suzuki DRZ110, Yamaha TTR90, and other 70cc to 125cc models. Before installing, always check your tire for debris like thorns or glass, and inspect the tube for leaks (the water bucket trick works great). Installation is straightforward if you’ve changed a tube before—just be careful with tire levers to avoid pinching the new tube. A handy set to keep in your garage for quick repairs so you can get back to riding faster.
