Product Overview

This high-quality Original Drive Belt is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2025) models.

The Drive Belt is a critical component of the CVT (Continuously Variable Transmission), transferring power from the engine to the rear wheel. A worn, cracked, or stretched belt causes slipping, reduced acceleration, loss of top speed, and in severe cases, complete belt failure. This original replacement is manufactured to original factory specifications, ensuring correct fitment and smooth power transmission.

Complete Part Guide

The drive belt is one of the hardest-working parts on the bike, especially in stop-start riding. The original Yamaha NMAX125 Drive Belt (B8R-E7641-00) for 2021-2025 models is built to handle that constant load, keeping power delivery smooth even in heavy traffic conditions. This ensures reliable performance day in, day out. Manufactured to the original Yamaha specification for exact fitment and durability. Available now from Part Hive, enjoy same-day UK dispatch on all orders before 1 PM from our London hub.

We often see NMAX-125 units come in where the drive belt already shows visible cracking or glazing, but the rider has continued using it under load. Once wear reaches this stage, the belt can degrade quickly, and as it starts to delaminate or lose tension strength, failure can happen with little warning, often resulting in immediate loss of drive. When it snaps, the scooter is left unable to move. We replace it early with the original Yamaha drive belt and it helps maintain consistent power transfer and avoids secondary damage to the CVT system.
