This 8 mm ultra-thick inner tube is engineered specifically for harsh off-road conditions, delivering maximum durability and reliability across rough, rocky, and muddy terrains. Crafted from high-quality, puncture-resistant rubber with an airtight seal, it minimizes the risk of flats even on the most demanding trails. Updated New Design: Zero Balance Issues! In our new generation production, the internal fixing mechanism has been removed, leaving only a reinforced valve stem structure. This update completely eliminates balance issues during rides. Beyond pure enduro and motocross bikes, it now ensures smooth, vibration-free performance at higher speeds on dual-sport and ADV motorcycles like the Honda CRF 250L and Yamaha Ténéré 700. Key Features & Innovative Design: • 8 mm Wall Thickness: Provides extra protection against punctures and heavy impacts, giving riders confidence on tough trails. • Rim-Contoured Form: Molded to match the inner structure of the rim, preventing the valve from flexing or getting damaged while riding. • 8 mm Valve Stem: Enables easy inflation and maintains long-term air pressure. Technical Specifications & Installation Recommendations: • Total Weight: 4.3 kg – 4.7 kg • Rim & Installation Tip: For extreme enduro use and optimal system performance, using 2 rim locks is recommended. For easier installation of the rim, valve, and rim lock, enlarge the rim valve hole diameter from the standard 8 mm to 9 mm and chamfer the edge slightly. Recommended Operating Pressures (Based on an average rider weight of 75 kg - 18" / 2.15" Rear Rim): • Good Off-Road Traction: 9 PSI • Mixed Enduro Terrain: 6 PSI • Hard / Extreme Enduro Terrain: 4 PSI
