The first oil change is the most important because that new engine is going to be wearing off uneven surfaces more than at any other time - and hopefully carrying away the remnants in the oil. Most manufacturers suggest 500 miles for the first oil changes - but I normally do mine closer to the 180 miles that Kymco suggests anyway.
Especially since you don't have an oil filter - I would suggest you replace your stock drain plug with a magnetic drain plug.

Even though most of the engine parts are aluminum - I always catch stuff on my drain bolt magnets. The transmission is probably the largest source. The wearing off of those bits is normal and good - having those bits get against piston sleeves or valve guides is not. On bikes with filters I've used magnetic oil filter wraps - but the drain bolt magnets seem to catch more. I would guess it is because the oil is moving through the filter really fast, whereas it moves through the pan much slower.
Magnetic drain bolts are one of those things that can get a lot of people debating. But most people will agree that BMW motorcycles are some of the longest lasting engines - and every BMW motorcycle comes from the factory with a magnetic drain bolt...
ok so what i suppose to do wait till i hit 500 miles or do it on mine own? but now i have about 160miles already and when i order tat magnetic drain plug it takes few days and then i will break warranty if i do it on mine own no???
btw when i bought last weekend s8 after one hour i checked tires and on rear tire was cracked like this,,,
i went to back dealer and they told me it was mine fault.. mechanic said i slash it or i ran over something,, they said they will send pics to kymco,,, if i ran over something i would get flat,,,duh,,,
so i dk what i supposed to do now,, i am stuck pretty much
yes bmw has best engines no matter what!!! either is car or bike,,!!
