Bel-Ray Thumper Gear Saver Transmission Oil 80W-85 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.


  • For all motorcycles equipped with separate engines and transmissions
  • Equally suitable for gear or chain primary drive

Features and Benefits:

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

General Description:

Bel-Ray Thumper Gear Saver Transmission Oil 80W-85 is premium transmission oil.   It provides maximum gear and bearing protection and smooth clutch performance for the most demanding off-road racing.  Anti-foam and anti-oxidant properties ensure the most effective lubrication and gear protection.
