When I read online or talk to folks in person about the best oils for BMW airhead motorcycles, I never see the Kendall products mentioned. I always thought Kendall was a nasty sludge maker like Penz and Quaker, but I know that was the bad old days and all brand name oils are way past that. Also, Kendall has always been associated with Harley. When I look at the numbers and the additive package, this looks like a great oil for airheads, which are very similar to Harley in terms of poorly controlled temps.) Any airhead guys out there use this oil with long-term results?
