For my '14 CB, I use Motul 7100, 10W40, 100% synthetic. No complaints at all. Perfect for my CB and me!!
Motoul 7100 is one of the best oils available.
Used it (10W60) in the Moto Guzzi at ambient temps up to 116 F and the V7II only took 2 quarts / liters.
The SoCal dealer prepped the Triumph with Castrol Power 1 20/50, so I continued with it. The Bonneville made a few trips across the Mojave desert. With dual oil pumps and oil cooler, it never acted hot.
The CB started out with GN4 (Nov 2017)
Changed at 519 miles for fresh oil to finish run-in
Switched to HP4S at 4011 miles, but only available in 10W30
Then I went with Castrol Power 1 10W40 (on the shelf at O'Reillys) at 8667 miles and continued until we had to part.
When I changed oil on the Ryker at 1200 miles, I switched from XPS (BRP brand, reported to be Castrol) 5W40 synthetic blend, rated for up to 104F (not enough around here) to Castrol Power 1 10W50. Available from O'Reillys on sale (not stocked) for $9.99 per quart...$10.79 (I think) normal.
All are 4T oils, so no clutch issues.
I am not promoting any brand, but strongly recommend a major quality brand, viscosity range appropriate for climate, pure synthetic and change more often than recommended.
