Wilfy, the title says 425 the listing says 428 ? :rollseyes:, it also says 30kg-cm that converts to 416oz-in and that is 2.9Nm.

It's so close i wouldn't worry too much, choose some 3Nm motors and crack on, have a good look at the specs, buying from a reputable source maybe somthing to think about. There are a number of manufacturers out there so model numbers will be different, its what is inside the motor that counts hence "reputable source".
