It utilizes Electrosyntec Technology and base materials derived from aircraft turbojet engine lubrication for outstanding wear protection, excellent load-carrying and high film strength properties. It is suitable for all high performance power units running on lead-free, low-lead or racing gasoline and has excellent detergent properties to ensure exceptional engine cleanliness. Its stable multi-grade characteristics give optimum protection and superior gear change characteristics. Ester-based, full-synthetic 4-stroke off-road racing engine oil. Advanced surface chemistry provides vital protection to pistons, cams and bearings even during cold start, prior to lubricant flowing. Excellent thermal and shear stability give stay-in-grade performance. High film strength reduces friction and transmission wear. Improves clutch "feel" and reduces wear even with aluminum plates. With Silkolenes proprietary Electrosyntec Power. Meets or exceeds API-SF and SG standards. Motorcycle 4T JASO-MA2 certified. Electrosyntec Power Technology: Introducing Electrosyntec Technology; powerful intermolecular forces bond low friction molecules to stressed metal surfaces by a process of electrostatic adhesion, significantly reducing friction and wear from start up to full power. This offers improved protection against engine wear, provides long-term performance retention, and, most interestingly, minimizes friction at crucial points in the engine to release hidden power. Electrosyntec technology was pioneered due to demands from Silkolenes racing partners for improved power and performance, and it utilizes Silkolenes own synthetic base material designed to their exact requirements. Put simply, Electrosyntec Technology extends the boundaries to provide the next generation of oil for the latest generation of bikes.
