1000 cc and skimping on oil?
On a car, the last thing I'd skimp on is oil.
With a motorcycle, I add tyres as well.
For a sport, recreation motorcycle, add suspension and brakes to the save a penny, loose a pound list.
This one has sloppy factory suspension, rather cheap tyres, but even there I use fully synthetic motorcycle (marketed) oil. I do always buy on discount, well in advance, but never use cheap oil. JASO MA2 for the clutch and fully synthetic.
Expensive oils are a ripoff - both for a car and bike, but I have no way of testing an oil. Not a laboratory, nor a test vehicle to run it for 100.000 km and measure wear compared to more expensive oils.
