Ready to install.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe V-belt sits between the variator and the clutch bell and transmits torque from the engine to the rear wheel. The dimensions 669×18×30 correspond to the original V-belt for 139QMB\/QMA engines with 10-inch tires, the standard size for this engine class. The material compound provides good grip for original and slightly performance-tuned engines. When the belt is worn, the variator slips under load and the top speed drops – replacement is a mandatory maintenance task.\u003c\/p\u003e\n\u003cp\u003eReplacement takes about half an hour with a variator holder, hex key set, and socket wrench for the variator nut.\u003c\/p\u003e\n\u003cp\u003eV-belt for scooters with 139QMB engine, made by Moturo.\u003c\/p\u003e\n\u003ch3\u003ePerformance · Material · Specs\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eDimensions 669 × 18 × 30, true to original size\u003c\/li\u003e\n\n\u003cli\u003eSuitable for scooters with 139QMB\/QMA engines with 10-inch tires\u003c\/li\u003e\n\n\u003cli\u003eMaterial compound with good grip for original and slightly performance-tuned engines\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eImportant notes – please read\u003c\/h3\u003e\n\u003cp\u003eOriginal spare part design, no separate ABE (general operating permit) required.
