I had a '06 Triumph Thruxton with a handle bar conversion. Great bike. Should have never sold it.
Have a V7C and it's a great bike too. Smaller than a Bonneville for sure.
My buddy Tom has a Bonne and he's a big guy. He took my V7 up the Skyway and while he liked the bike, it didn't fit him. It was too small for him to be comfortable.
You need to give both a test ride if you can. I have a friend that purchased a Guzzi Nevada and hated the side to side torque. He sold the bike after a couple months. Too bad he didn't test ride it before he purchased it.
