I typically use mobil1, but in the past i heard that Red Line was one of the few that actually sells "true" full-synthetic whereas everything on the shelves were just really syn-blend. Red Line is way out of my budget, but it would be cool to try.

Use Honda Pro Oil and save yourself some money. Redline is too expensive for my pocket book.

 

I have royal purple in my bike and its $16.00 a quart so red line is cheeper

 

If you're in the market for expensive "true synthetic" oil then pick up some Amsoil. I believe you can even get a discount through this site as they are a sponsor.

Don't get too wrapped up in oil though. It will make your head spin. I've lost far too much sleep looking up test results from used oils and which are true sythetics and what kind of synthetics and which actually work well and which break down too quickly and... you get the point. It can make you go crazy.

Honda pro is just fine. I liked Repsol because it seemed to make my bike shift smoother.... but to each their own.

 

I used it for about a year, no complaints. Now I'm using Amsoil because its cheaper and don't notice any difference.
