Spectro Heavy Duty STL Transmission Oil Specifically Engineered For The Harley Sportster Engine.

HeavyDutySTLSpectro Oils of America, based in Brookfield, CT, has launched the Platinum Heavy Duty STL Harley Sportster Transmission Lube. Spectro 6 speed synthetic technology is now available for the Harley® Sportster and Buell®. This fully formulated synthetic transmission lubricant is engineered to work in all applications where the same oil lubricates the clutch, primary, and transmission.

Spectro STL is a high-performance lubricant that provides superior performance and delivers the highest levels of protection for the Sportster drivetrain. Proudly made in the USA, with an API GL-1 rating, STL exceeds all known OEM and Harley-Davidson® warranty requirements.

Spectro Oils Vice President of Sales, Rollin Karoll explains, “Since the introduction of Spectro “6 Speed” transmission lube for HD big twins, Sportster owners have been asking for a lube of their own. That day is now here with the introduction of Spectro STL; Sportster Transmission Lube. Like our industry leading Heavy Duty 6 Speed Transmission lube, Spectro STL provides easier shifting, less gear noise and reduced heat for Sportsters. Our proprietary wet clutch formula also reduces clutch chatter and slippage. If you ride a Sportster, this is the transmission lube you’ve been waiting for!”

Allen Scott of Florida states, “I’ve always hated the way my 2005-1200R Sportster shifted, especially when it’s cold! The shift between first and second gears was never any fun, and neutral was just a pain while at a red light. Spectro had me test the new Heavy Duty Platinum STL; full synthetic sportster transmission lube, and now my bike shifts as good as my Road Glide. The Sporty transmission is now quieter and easier to shift and it finds neutral right out of the garage! Well done, Spectro!”

Spectro brands are manufactured and marketed by Intercontinental Lubricants Corp. of Brookfield, CT. ILC is one of the world’s foremost manufacturers and packagers of quality, specialty lubricants. The Spectro® line also includes superior suspension fluids, fork oils, brake fluids, coolant, chain lubes, filter cleaners/oils, and appearance products.
