yamaha bikes come with another liquid inside the motor. it is olso kind of oil but you canot start the bike with it. this kind of oil keeps the bike engine parts wet and out of rust and stuff like this. One of the dealer's preperations steps is to take this oil out and put a real oil that uses for the first 600m then you have to change it again.
That what my dealer did when I got my bike. I saw him doing this.
I don't doubt that in the least, downtown, because I don't know what Yamaha sends to Israel.
With the bikes that come to the US, at my local dealer, the oil in the engine upon delivery to the dealership is what is usually in it when it is delivered to the customer.
In fact, nowhere in the Yamaha Assembly Manual (printed in the USA) for any of their bikes assembled by US dealers have I ever read about having to drain the oil before fire-up - and I've assembled both of my R1s, my R6, and my FZ-1.
In fact, I'm reviewing my YZF-R1K (1998 model) Assembly Manual that I have left in my tool box from that time, and the only thing mentioned about oil is making sure there is enough and adding if needed before you hit the START
