I had the opportunity to ride this bike before it was introduced to the public when I worked at a Triumph dealership. My previous cruiser was a Kawasaki Meanstreak which at the time was hands down the best sport cruiser on the market.
The Thunderbird with the 104 cubic inch motor blows it completely out of the water. It is without a doubt the best riding cruiser available to the public today. Comfortable, powerful, great handling, awesome brakes. It is the total package. Go ahead and take the peg feelers off, you're going to grind them off anyway the way this thing handles.
Get the shorter Triumph pipes, the ECU is programmable. It is awesome.
