Bel Ray Thumper Gear Saver Transmission Oil is a premium 4-stroke transmission oil that has been developed for the unique demands of 4-stroke motorcycles equipped with separate engines and transmissions. Formulated with extra protection for gears and bearings subject to high torque loads of today’s powerful 4-stroke Thumper engines. This multi-viscosity formula flows freely for better clutch cooling and provides positive clutch engagement for better starts and longer clutch life while protecting highly-loaded gears from wear, ensuring smooth shifts for more positive action..

Features:

• Eliminates wear by chemically bonding to gear wear areas
• Prevents metal to metal contact caused by heavy shock loads during on/off throttle operation
• Special lubricity additives cling to metal surfaces reducing internal friction
• High film strength and reduced film thickness lower internal drag and heat build-up
• Prevents viscosity loss due to shear
• Meets the frictional requirements for improved grip and smooth power transfer without clutch slippage or grabbing for consistent hole-shot performance
• Meets or exceeds API GL-4 and GL-5 requirements.
