100% Synthetic and fuel economy Engine lubricant based on Ester-Technology. This lubricant is specially designed for high performance bikes (sports bikes, street & road bikes, trails, off road bikes, enduro, trial among others) with integrated gearbox or not requiring API SN standard. It fits wet and dry clutch, engines designed to run low viscosity lubricant and fitted with exhaust gas after treatment systems (catalytic converters, air injection into exhaust pipe). Based on Ester technology, this product in reinforced in low traction coefficient Ester to minimize engine internal friction losses and improve performance. This synergy of Ester with anti-wear additives and improved shear resistance improves gera protection and lifetime. It ensures better operating contitions of the catalytic converters due to phosphorus and sulfur contents. It offers the most efficient friction levels to guarantee the clutch engagement during the three riding modes: Starting, acceleration and constant speed. The API SM standard is fully backward compatible over API SL standard and all former API standards. Suitable for catalytic converters. Suitable for specific KTM, HUSQVARNA, MOTO GUZZI engines requiring SAE 10W-60 viscosity grade oil.
