For Oil Changes???
NO, those are the recomended intervals to do checks and mantanence on the bike, 600 is the first inspection and tightening of bolts, gives the dealer a chance to make sure they put it together right, without looking at MOM I know 15,000 is the first valve adjustment, other things such as coolant, brake fluid, and other adjustments are built in.
Oil, is 600, 2000, and every 3000 after, recomended, the first change is a must to get the break in oil out of the engine.
Check MOM for a complete list of adjustments
As for oil use you own discresion for when and what type/brand to use.
Many wars have been started over the question "WHAT IS THE BEST OIL TO USE", each to his own, its your bike. (NOTE: Do not use car oils most will ruin your clutch)
The maintanence should be done, within reason on schedule, if you are a "wrench" do yourself, if not, like me
have the dealer do it, hope you have deep pockets).
Good luck and keep the shiny side up.
