Friction Modified Thumper Racing 4T Engine Oil & Thumper Gear Saver Transmission Oil
Introducing, the New Friction Modified Thumper motorcycle oil, specifically formulated for motorcycles with separate engine and transmission oils. This exciting new product contains friction reducing additives that lower the drag on all moving components of the engine, reducing the heat generated by friction and increasing horsepower output.
Bel-Ray Friction Modified Thumper Racing 4T Engine Oil is a JASO MB rated 4-stroke motorcycle oil and should only be used in engine applications, never in a wet clutch application. By using friction reducing additives, lower SAE viscosities reduce horsepower-robbing fluid friction to increase horsepower output. Friction Modified 4T is available in both 10W-30 and 10W-40 viscosities.
The best applications for this product are the Honda CRF 250R and 450R.
For use in the wet clutch found on the Hondas, we recommend another new Bel-Ray product. The Thumper Gear Saver Transmission Oil 80W-85 is multi-viscosity transmission oil that will provide the lubrication needed as the transmission and wet clutch heat up during a race.
Bel-Ray Thumper Gear Saver Transmission Oil 80W-85 can also be used in all 2 stroke racing applications.
