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 Silkolene's racing partners for improved power and performance, and it utilizes Silkolene's 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. Don't miss out on this fantastic opportunity, demand Silkolene Electrosyntec Oil Technology!

Switched to this oil from Bel-Ray Thumper and am really happy with it. The motor has quieted down a little. Also heat robs alot of power from my bike and I feel the bike is cooling faster and loosing less power on extended rides

Silkolene Pro 4 is the Best

Recently switched to Silkolene from Motorex and I have to tell you that after a full weekend of racing stuff still looks and smells new - as the Motorex was black and smelled burnt Highly recommended A+

Good stuff

I have always used Silkolene products and have never had any problems. I started with pro 2, and my pistons always looked brand new. Everything I heard or read indicated this it top quality stuff. I also love Silkolene Pro Prep, just spray your whole bike with it and it looks better than new (dirt bikes only). It also cleans easier after the next ride.
