Product Details

Gates built the G-Force RedLine line for CVT systems that see higher load, heat, and speed variation than standard street-duty belts. This belt’s notched design helps it flex through the pulley system, while the aramid reinforcement and EPDM construction support durability in extreme off-road use. For buyers searching for a Gates 40R4313 CVT belt, a RedLine replacement belt, or a high-performance CVT belt for powersport drivetrains, this part is built around those requirements.

This part cross-references Yamaha XS825 and Yamaha XTX5058 for the same application. It is also listed under Gates 40C4313 and Gates 40G4313 interchange references.

What It Helps Address

• Slipping or inconsistent CVT belt engagement
• Reduced acceleration from a worn transmission belt
• Speed ratio loss under load
• Heat-related belt wear in off-road use
• Loss of top-speed performance from belt stretch or glazing

Installation Notes

Verify belt dimensions, pulley profile, and CVT specification before installation. Match the 40R4313 part number to the vehicle’s required belt size and section profile, especially when servicing Yamaha CVT applications. Inspect pulleys, clutch surfaces, and belt alignment during replacement to help prevent premature wear.

Fits select Yamaha CVT applications; confirm year, model, and belt specification before ordering. Common search terms include Yamaha XS825 CVT belt, Yamaha XTX5058 replacement belt, and Gates 40R4313 CVT belt for powersport drivetrains.

Quality Assurance

Gates manufactures the G-Force RedLine CVT Belt line with OE-improved design intent for performance-focused CVT service. The belt’s aramid reinforcement, EPDM compound, and double-notched construction reflect a specification-driven approach for demanding powersport use.
