It indicates that you are country, but the official dealership must provide original spare parts, they are not allowed to sell second brands, maybe the place where you call the dealership is only a point of sale of an individual. I am from Argentina I am a motorcycle user honda , and in the city where I live there is a shop and workshop with the signage of Honda as a dealership but only sells on behalf of a dealership of another city and there if you have spare parts of all hair but in the dealership there is only of the Honda brand .
Amigo sends an email to Yamaha Argentina and confirms that it is an official agency and whether or not it can sell parts of second or third brands and for example an original CDI costs 4 times more than a trout, they show you the CD in its original packaging , they put the trout that can be as good as the original and they charge it as the orig. for things like this they should not sell second brands.-
