I have a yfz450 and a street legal ttr250. I run this in both. Not by choice so much. Its the only 10w30 i have found for the bikes that is synthetic. Its been good so far no probs. but there is prob. better stuff out there. Ill stick with it tho.

I change the oil very frequently (3 hours). Everything has continued to last me i will continue to use gn4. If you don't do frequent oil and filter changes i suggest going with the HP just to be safe.
