Just FYI, the Scott website says it comes with Serfas silicone grips, which are claimed to weigh 55g. So unless you know of grips that weigh -5g, you won't be saving 60g there!
Did you link to the wrong bike? Are you sure you didn't mean to link to the Scale 700 (650b) RC?
Those wheels aren't bad by any means, you'll have to spend quite a bit of money to upgrade them. Most of the Stan's wheels would be a downgrade, IMO.
The handle bar and stem could both be swapped for something a tad lighter, but you'd be spending big money for little savings.
So after swapping the wheels, bar, seatpost, ti bolts, and powercordz, you might
be able to drop ~300g. But honestly, I think that's probably a stretch.
If you really wanted to get it to 8kg, change the fork to a lefty, and get some of of the new Tune carbon rims laced to extralite or mack hubs. Then do all of the other things (bolts, powercordz, bar, saddle, seatpost, etc.).
It's a nice bike, ride the hell out of it.
