4. A Triumph motorcycle. Could be the Thunderbird, or maybe the Bonneville, whatever, as long as it's at least a 650.

This one's a heavily modified Bonneville 2007, with dual fuel-injected carburettors, and dubbed the Hiawatha.
Personally, I'd prefer they kept the front mudguard.

The photo was, I think, taken by Joel Bessa, and is taken from the modifier’s website: http://www.tonupgarage.com
