Bel-Ray V-Twin Sport Transmission Fluid 1 Liter

Bel-Ray V-Twin Sport Transmission Fluid 1 Liter

The Sportster XL runs engine, transmission, and primary clutch through a single shared oil sump — placing unique demands on the fluid that a general-purpose transmission oil cannot meet. Built specifically for that architecture, this Sport Transmission Fluid keeps clutch engagement crisp and consistent, quiets gear whine, and protects the sump from wear between services.

Key Features

• Formulated specifically for Sportster XL transmissions and primary gearboxes — services both compartments simultaneously in the single shared sump
• Extreme pressure additives protect highly loaded gears and extend transmission service life
• Prevents clutch slipping and chatter for consistent, positive engagement
• Flows freely for improved clutch cooling and longer clutch life
• Resists oxidation and viscosity breakdown for extended drain intervals
• Quiets gear whine and improves shift quality
• Distinctive red color for quick leak detection

Fitment Notes

• Also compatible with Buell Blast motorcycles per Bel-Ray manufacturer specification
• Not compatible with the 2021-Up Sportster S (RH1250S) — the Revolution Max platform uses a different engine architecture and lubrication system
