Torco makes great products. I ran their 50wt Dino oil in my 02 Road King. My Indy swore by it. Keep us posted on your results with the 25-60 synthetic and the noise reduction.
If you read Amsoils report on oils, Torco ranks pretty high is most of their tests.

OMG, I used Torco 50wt dino back in the late '70s early '80s in my shovel. It was great oil back then. Most of the local indy shops carried it and was 'the' preferred performance oil of the day.
The reason that you don't see it on anybodies shelf is because it goes for over $21.00 a quart. Torco specs the oil out and has somebody else formulate and bottle it. Kind of like Harley does with Hugo Chavez or whoever the hell.
