Rotella is a HDEO (Heavy Duty Engine Oil) and is probably more stout than any "motorcycle" oil on the planet. It' a VERY good oil and was made to be run in diesel engines under extreme pressures and heat so it'll more than hold up to anything you can throw at it in a bike. Their are many, many threads on bobistheoilguy.com about rotella in all orts of bikes from air cooled harleys and victorys to high end RR's and they all do fine. Their are a lot of oil analysis results on there too that show how good it holds up under use.
Just run it and a good filter like a K&N or napa old and go enjoy the bike. People worry waaaaay too much about oils nowdays. Pretty much ANY modern oil is a good oil these days, even the dino oils have plenty of additives and stuff in them to easliy run 5,000 miles with a good filter. The only oil you do NOT want to put in a bike is an automobile oil that is "energy conserving" because it has friction modifiers in it that will make your wet clutches slip and ruin them. With the quality of modern oil people NEED to focus more on what filter they run. I see idiots all the time with a jug of mobil 1 and a fram filter! Fram filters are complete garbage along with several others on the market. There's many tests out there of all the different filters and how they perform and how they're made along with several youtbe videos howing the internals. The main good one's are purolators (both classic and the pure one), K&N and the napa golds along with some others I'm forgetting about.
Here's great read on filters!
