Hey fellas, quick question. I've just recently built an 08 600RR track bike and had some concerns about the oil. Does everybody here use the recommended 10-30? My question is what oil do you use if you know the bike will hardly ever see below 10K rpm. Factory specs or a heavier oil? I am currently using royal purple 10-40 m/c oil and just wondered what everybody else uses as far as oil/filter combo in their track bike (not street/track bike). Thanks in advace.

 

Repsol 10W40 in the track/race bike, stock filter.

 

You can save a few bucks by switching to a car oil, even if you increase your drain intervals. I would do an filter change and then oil change at whatever interval you decide.

 

Cost isn't so much of a concern as the is the weight. Wasn't sure if 10W40 was too heavy. Thanks for the input.
