LOCOMOTIVE POWER 4T 20W50 SN is an advanced engine oil designed to fulfill the rigorous requirements of motorcycle engines. It is specifically tailored for on-road, high-performance 4-cycle sport bikes but is also suitable for various other on and off-road 4-cycle motorcycles. Engineered to provide exceptional protection, it excels in 4-cycle, V-Twin engines, particularly those that are air-cooled and operate at higher temperatures compared to other engine types. LOCOMOTIVE POWER delivers outstanding performance in both integrated engine/ transmission lubrication systems and in systems where the engine and transmission lubrication are separate.
