Designed with precision engineering, this offers unmatched performance and durability.
There's a point where replacing individual parts isn't enough. Once the gears are worn, the noise is constant, and the performance drops, the whole system is telling you it's done. This original Yamaha NMAX 125 gearbox transmission set (B6H-E7421-NMX) resets everything internally, bringing the drivetrain back to smooth, controlled power transfer without the noise and resistance.
Vetted by our Lead Engineer. Leveraging 30 years of mechanical pedigree, every part is inspected for material density and exact tolerances to ensure a 'Right-First-Time' fit.
