TFC Forged Racing Outer Drive Face - Honda Dio / Elite 50
Description
This TFC forged racing outer drive face is a lightweight outer CVT pulley outer drive face for Honda Dio and Elite 50 S/SR performance builds. Its 128 g forged-aluminum construction reduces rotating mass to help your engine respond more readily when you open the throttle. A multicolor finish, splined center, and 62-tooth outer starter gear give this transmission upgrade a distinctive look to match its racing purpose.
Key Features
- Lightweight response: The 128 g drive face helps reduce rotating mass for a more responsive CVT setup.
- Forged aluminum: Combines low weight with strength for performance-tuned transmissions.
- Heat dissipation: Aluminum construction helps shed heat during demanding operation.
- Outer drive face: Replaces the fixed outer pulley face rather than the movable variator assembly.
- Distinctive finish: Multicolor surface with TFC Zero Racing lettering, a splined center, and 62 outer starter gear teeth.
