How you break-in your bike determines how dark and nasty the oil will look at any particular mileage up to 600 miles. If you do a hard break-in, it will be quite dirty, even at 100 miles. Mine was quite dark and had shiny particles of metal in it. The filter was full of gunk as well...at 165 miles. When I say hard break-in, I mean I warm the bike up thoroughly by riding 10 min. or so, then I accelerate in 2nd or 3rd gear up to redline and immediately let off the throttle completely and let the bike slow back down. The gear doesn't matter but if you do 2nd or 3rd with this bike, you won't likely be speeding too much at red line. You could do it in 1st gear, but 1st gear is harder to control. You then repeat this several times. In addition you go up and down the gears varying the rpms dramatically. You don't even have to speed necessarily or accelerate fast to break-in this way. I can't say it's better or worse, but it is faster.
I use Rotella T6 in all my motorcycles and have for years. It is full synthetic 5W40 and carries the JASO MA rating. Although not specifically formulated for motorcycles, it meets the specs. Available at Walmart for $22 a gallon, cheaper if on sale. There is one theory that you shouldn't go to full synthetic until 1000 miles or more, but some motorcycles come with full synthetic...bikes like the RSV-4, Tuono, Vespa, even the small Sportcity scooters come with full synthetic AGIP 5W40. My Triumph Street Triple R came with full synthetic and so did my Prius V and Honda Civic, so many cars and motorcycles come with full synthetic.
