I’ve used Shinko (Ravens?) on my SV650 and they did the job a-ok. In fact, the legendary Buell whisperer “lunatic fringe” ... may his soul Rest In Peace, was affectionately referred to as “Sargent Shinko”.
For what it’s worth, I often look at the tires one puts on their motorcycle as a sign of it’s care and use. Sort of like a pair of shoes. I’m not going to knock you for your choice as it’s a practical and prudent move. However, if you were selling the bike and I was looking at it and spotted the Shinkos, I’d wonder what else you took the path of saving money over quality. But you’re not selling it, so that’s a non-issue.
