Just wondering if anyone has used Royal Purple oil in their bike or has heard anything good or bad, or is there another oil that is better?

 

I haven't heard of this brand before. I typically use Honda's dino, or Motul synth.

 

I use it in mine, and we have a sponsorship from them in Baja, same with our formula team. We've found that it makes the best power over Mobil and Valvoline synthetics.

As for my bike, I love it. Cooler, more constant running temps, no problems with the clutch. Only compliant is that I get a lot of seeping, but I also run the equivalent of 5W-20 weight, very thin.
