Same as Paul
I did 12,500 miles in 12 weeks (first and last week in a hire car) in '04 but I bought a bike as getting a bike back from my end point, Seattle, involved expensive air freight. I decided to go as a late decision and only bought my ticket 3 weeks before I went so sea freight there was also out of the question as I'd missed the boat.
So I bought a mint 1100GS already equipped for 'adventure motorcycling' for $7500 and sold it at the end for $5250 with a pair of completely shagged tyres and in desperate need of a service.
Buy if you can because although its great to take your own bike and then bring it back, when you add the cost of tyres and mechanical wear & tear PLUS depreciation to the already expensive freight costs it aint cheap.
As previously said you have to spend some time in Moab. Awesome. All the parks on the doorstep, river rafting , jeep hire onto the White Rim trail. I also loved Bryce Canyon even more than the Big GC. Mesa Verde was good and also the often overlooked Canyon de Chelly which isnt far from Monument Valley.
Stick to Colorado and Utah/Arizona and you wont be disappointed. The roads may be straight and in theory boring but I can assure you that you will not tire of the amazing scenery! The emptiness and the vast open spaces are breathtaking.
Be prepared for riding at altitude, you will still need warm clothing even though daytime temps are good.
One of my favourite roads was Scenic Hwy 12 which knocks around the Grand Escalente area covering GC, Zion, Bryce etc . I can also tell how to do a great ride on fire trails to the North Rim of GC which will take you well away from the usual tourists and allow you to ride right to the rim instead of right into a car park next to a visitors centre. Although I have been told that the main highway to the north rim is also one of the best biking roads in the Sth West, unfortunately I was there first week of May and the road was still closed.
PM me if you need any info' or advice.
Have a great time
