My ride, a Yamaha Venture Trans-Continental (1900) is running smoothly with this oil, the engine and the transmission. I used this kind of oil before, on Kawasaki Concours 14 and on Yamaha Roadliner. It's a very good oil and you may do a lot of kilometers ( more than the norm) with the same oil without any hassle.
When the best product is available....you use it!!

This synthetic oil is great!! It provides much better lubrication for my 2018 Can-Am Spyder RT Limited SE-6 with the 1330cc ACE engine than the XPS stuff than the manufacturer suggests. After changing to this oil from the XPS garbage, my engine runs quieter, cooler, and shifts more gently. I will stick with this oil!!! Plus it's cheaper than the XPs stuff and I can order it directly.
