HP4S - SportsterDoc - 11-19-2017
Honda parts may be expensive, but their lubricants are competitively priced.
Been researching Honda HP4S pure synthetic as an alternative to Castrol Power 1.
It appears to only be available in 10W-30...but maybe this brochure is not up-to-date?

If that is correct, and if I continue with Honda oil, the debate is synthetic 10W-30 versus GN4 10W-40 for 115F + ambient.

The brochure shows it to be a Spring 2008 publication.

Yep, have you seen a newer one? I have not (but I have looked for a newer one).
