Dual tires for Honda Shadow?
 

Off to Yosemite and Sierra Nevada and wherever in June. I'll have my hang glider and gear in my pickup and can tow one motorcycle. I would bring my KTM 640 if was only me, but my wife will be with me for~1/2 the time and the 2001 750ish Shadow is way more comfortable two-up. I know it's not a dirt bike!
I want to replace current road rubber with tires that might work a little better when I get tempted to explore dirt/gravel roads, but still quiet and will hold a lean into sweepers.
On it now : Bridgestone Exedras G702 170/80-15 77S and G701 120/90-17 64S
Any advice appreciated,
