hmmm, I'm starting to think I have owned a bunch of boring bikes.
If any bike can be considered boring.
I'm gonna say any big metric cruiser. It's a relaxing ride, but has the punch to leave the 4 wheel traffic sucking wind. Mike mine an M109R, please.
Honda NC700X. I haven't ridden one, but I would sure like to own one. Very user friendly, well balanced, ergos are perfect, and it's got that fantastic storage area. What's not to like?
Honda GL1800. Take it down your favorite curvy road and prepare to be amazed. Great handling, luxurious, and power to burn.
V-Max. Pay for your funeral first.
Kawasaki Ninja 1000 = because I just need to know what it's like to ride something so competent.
Motus - need I say more?
