I did Adelaide to Junee in a day last October (920 kms) and Melbourne to Sydney via the alpine route (945 kms) the year before.
The Sprint is a great bike to do this sort of distance. Great fuel consumption with an indicated 110 on the clock (that's about 102-103 so you'll have no trouble with the law).
Make sure the tyre pressures and fluids are spot on and be prepared to have a walk (jog)
around and a good stretch for 10-15 minutes at re-fill time. I also take a container of sultanas and various nuts because a stomach heavy with food is more likely to bring on fatigue as you digest it.
Plenty of water to keep hydrated (coffee will make you want to pitstop too often).
Wear ear plugs and buy a throttle rocker. I always wear a scarf tucked up under the sides of my Shoei and that further cocoons from noise which is a big contributor to tiredness. Wear enough clothing to keep you snug but not toasted.
And if you DO get too tired a hotel can be had for $50... because we'd like to hear back from you afterwards.
BTW...I'm on the high side of 50 so your age shouldn't be a factor.
Have a ball!
