The surface on the pass is actually pretty good. I'd give a good 7 (maybe 8) out of 10. It would be firggin' awesome on your bike though. The weird camber changes would likely cause you less trouble than they do a car. The trick is to wait at the bottom, to ensure no one is in front of you. There's almost no place to overtake easily.
And yeah, the pies at Robertson are significantly better that servo pies. Still, nothing beats a beef brisket pie from Bourke Street Bakery. Brilliant pies. Even better, are the lamb and harissa sausage rolls. Made with real BUTTER, so you don't get that horrible dry mouth feel. Amazing sausage rolls. Best of all, Bourke Street Bakery opened an outlet at Kirrawee! About 4 clicks from Sunny Oyster Bay. NEVER go to Bourke Street Bakery (any of their outlets) at lunchtime. The queues can be phenomenal.
Two more things:
1) Don't do the pass on the weekend. You'll almost certainly get stuck behind a Land Cruiser, or something similarly useless. Take your sunglasses off. You won't need 'em. The funniest part is that the posted speed limit is 60kph. It's actually pretty difficult to exceed that speed in a car. A bike like yours is another thing. I hit a little over 100kph in a few spots. I couldn't stand the squealing (from SWMBO) though, so I slowed it down a bit.
2) For a more challenging drive/ride, try Jambaroo Mountain Road. Slower, tighter and narrower. It's often wet too. Lots of water seeping from various places onto the road. Best bit? Trucks are forbidden from JMR. I've only driven JMR once.
