This variator drive face pulley assembly is engineered for YMH NMAX125/NMAX150/NMAX155/XMAX125/MBK OCITO N-MAX/TRICITY 125/155 models, rigorously tested to ensure CVT system compatibility.
Features CNC-machined ramps with reinforced bearing structure to minimize belt friction, delivering smoother shifting and improved throttle response.
Constructed from high-strength aluminum alloy with specialized surface hardening, maintaining dimensional stability under sustained high-RPM operation.
Manufactured to specifications with precisely matched mounting holes and belt contact angles for direct bolt-on installation.
The refined variator profile keeps the engine in optimal power band, providing more responsive acceleration for both urban and highway riding.
Adopting a combination of aviation aluminum alloy variable diameter disc and high carbon steel ball bearings, the speed response speed is increased by 25%, and the acceleration range from 0-40km/h is specially optimized to solve the problem of factory starting fatigue.
The service life is twice that of ordinary modified parts
