That was the object of the exercise really, to see what difference I could feel from the oil.

The viscosity at 40C for the 7.5W RSF (37cSt) is higher than the Motul Medium 10W (33.7cSt) it had in before, but significantly it has a very much higher VI (322 vs 115), so by that reckoning they should be similar at normal summer running temps but the Silkolene RSF shouldn't get the sticky/stiff/lumpy feeling when it's cold that I certainly felt with the Motul.

Time will tell, it certainly feels more supple over bumps and holes, more "comfy" really, I'll see how I get on with it. Having said that, new oil always feels better.
