Got a small dirt bike that needs new inner tubes? These RUTU heavy-duty tubes are perfect for your 49cc, 50cc, or 70cc motorbike with 10-inch tires between 2.5 to 2.75 inches wide. They work with all the popular models like CRF50, XR50, PW50, DRZ70, JR50, Razor MX650, and Motovox MVX70. The thickened butyl rubber material is what makes these tubes special - they've got great air tightness so they don't leak easily and they're way less likely to blow out compared to cheaper tubes. That thick rubber also acts as extra shock absorption, smoothing out those bumpy trails and making your ride more comfortable. The TR4 straight valve is easy to access for air checks, and the upgraded copper dust cap gives you better sealing against water and dirt getting in. If you're tired of fixing flats or dealing with tubes that can't handle rough terrain, these will save you so much hassle. They're built to last through multiple seasons of riding, whether you're on motocross tracks, trails, or just tearing around the backyard. Installation is straightforward too - just make sure you've got the right tire size and you're good to go!
