A "very sophisticated product" indeed. Here's my story: this past spring, I changed the oil routinely on my 2016 VFR 1200X. This bike has a dual clutch transmission. Although I had previously used Motul 5100 10w40,(semi-synthetic) this time I used Honda mineral oil, 10w40. As time went on, I became aware of a troubling increase of "klunky" shifting. Unlike a number of other Honda DCT models, this one required a dealer connection from the bike to Honda's system, using a laptop to perform a re-flash. That got done, but any improvement I noticed, was negligible. Happened to have a conversation later with one of the WoodSToc attendees about my troubles. (well after, not during the rally) He related a story of a malfunctioning differential in a four wheeler, which was remedied with changing to the correct oil. (Thanks Brent) The local Honda dealer didn't have any suggestions, so here's what I did - changed the oil! Used Motul 7100 (full synthetic) 10w30 . My owner's manual specifies 10w30. Just completed this yesterday, and went for a half hour ride around town, with lots of shifting, both in road and sport modes. No more klunk! Although the shifts aren't perfect or like new, they're much improved. From the Motul site: Synthetic technology 4-Stroke lubricant – Ester technology - Meets bike manufacturer specifications, especially HONDA which recommends SAE 10W30 for fuel economy improvement. Smooth shifting. Improved shear resistance. Meets JASO MA2 specifications for optimal wet clutch performance.
So do pay attention to manufacturer's recommendations!
