Hey guys. I just picked up a leftover 2007 Kawi ZX-10R ninja new from the dealer a few weeks ago. I'm coming up to the 600 mile service. My question is what's a good synthetic oil for these bikes. I searched a bit but didn't really find much as far as street bikes. I checked the bike forums but I don't think they really know what they're putting in their crank case. They don't do UOA's or anything like that so they just tell you to use whatever they use. Any recommendations? Thanks in advance.
