Motul NGEN-5 10W-40 4T is a modern, sustainable motorcycle engine oil designed to deliver reliable performance with reduced environmental footprint. It’s formulated as a semi-synthetic blend (regenerated oils + synthetic esters) to offer good protection and durability while supporting eco-friendly practices. The viscosity grade 10W-40 makes it versatile in moderate temperature ranges and useful for both daily commuting and recreational/off-road use. It’s particularly useful for bikes with catalytic converters or secondary air injection systems, because its additive package is tailored to protect after-treatment devices. The oil is suitable for a wide variety of 4-stroke motorcycles, in both integrated & non-integrated gearboxes, with wet or dry clutches. Overall, it's a strong mid-tier option for riders who want decent protection and sustainability without paying the cost of a full synthetic top-end oil.
