What kind of oil in in the bike from the dealer?

Normally the dealers receive crated bikes dry (no fluids), and they then proceed to fill it with oil and other fluids. I'm only assuming here, but I would think their contracts with the bike manufacturers stipulate that the manufacturer's branded oil be used, and again I'm only assuming, but I would think that many dealers will use whatever oil is the least expensive for them and therefore best for profit margins.

Is it mineral oil that's in the bike? I'm still in the midst of break-in, but thinking of changing the oil.

NO, not in the engine. Mineral oil can be a substitute for brake fluid, but it requires different seals than conventional brake fluids.

Of course, this ^^ is correct, and I had I assumed the OP meant conventional or dino oil, as opposed to synthetic, when he wrote "mineral oil". I've known a few other people say the same thing.

I really mean mineral oil. Such as:

Which meets all the requirements put down in the owners manual.

Or is this some way to say "not synthetic" these days?

Bel-Ray is using "mineral" to mean "conventional" oil, i.e. not synthetic.

Using this terminology is confusing because "mineral oil" normally refers to the food-grade, odorless, colorless kind, which is commonly used as a laxative, as a make up remover, and as a cutting board conditioner.

My dealer told me the bike came filled with oil....not sure what weight though.

Initial break-in oil is likely a non-synthetic - just call your dealer and see what he's using. My dealer said as far as he knew, they just use regular Yamalube break-in oil.

Most likely 10W-40.
