....for my ZZR1400. I managed to get Castrol RS4T for £6 per litre. Looks like it's been superceeded by another RS4T oil that is about £10-11 per litre.
Any body have any opinions on the RS4T? It's fully synthetic 10W-50.

I cant see why any production motorcycle engine needs anything more than any decent semi synth oil, just change it regualary along with the oil filter...Do Kawasaki recommend that the 14 is run on fully synth?
