Yes, we are very close to Mt Nebo, and Mt Glorious both are very twisty roads and popular with motorcycle riders of all sorts. A lot of road racers get on both of them, cars and bikes. I first did Mt Glorious on an old Honda CX650 Euro. It's a V-twin much like the Moto Guzi's. Went with my nephew who nearly passed out as he was so caught up in the ride he literally forgot to breathe on the twisties. Last time I was up there I took my '97 GTR1000 (ZG1000), the roads were wet but I had new tyres and the bike loved it. So did I!
Got to throw a new back tyre on before I take the '02 GTR up there.
Look up Mount Glorious Road, Queensland on Google maps and zoom out you'll see how twisty it can get. You'll also see Mt Nebo Rd in yellow near it.
