What about heavy and larger items like beams, or rudder stocks as well?
Again a beam is driven by stiffness, so better take alu or even better CFRP.
Rudderstock, hm never thought about it. The rudder head, where the rudder pivot is fixed, could be made of titanium space frame, the bolts and so on as well. But the weight saving is small.
Actually i don't know about motorcycles, but on bicycles, Titanium was more for fashion than weight/stiffness, at the end CFRP was lighter, but Titanium was rare, a statement of style like a exclusive watch, mystic soviet technology...
