My street bike is a bit more fancy and clouds your question on if its a lockup or a slider.  How about, it depends...   Some rules would require a hand clutch, but what does that really mean?  :-DD

Yet many modern automotive engines run EGR for which you should use an EGR rated oil.

A little story if I may....
A lifelong buddy changed his work van, loaded with 500kg min and everyday at least another 500-1000kg of goods to install at work.
It was his first turbo diesel and asked his mate, a Valvoline rep for a oil recommendation to run in it.
He is a fastidious owner and every vehicle he owned was always very well serviced.

The change period was specified at 5000km however increased oil consumption started occurring at 3500km and he needed topups before the change period was due.
He asked for advice and quick study revealed the engine in this van had an EGR system and specialist oils were specified for it.

BS he told me but I insisted rather than continue to use the muck he was, instead visit the local auto everything shop and get (brand, type) oil pack for his next change.
He did and oil consumption before the next change period miraculously disappeared.

There's very good reason why I go to significant effort to disable any EGR capability........

For the base weight your clutch would certainly comply.  ;)
