The Speedmaster is the single worst bike produced by Triumph (not counting the Bonneville America) in it's history, and I'm including the Tigress scooter in that comparison.
I'm sure it runs fine with it's made-in-Thailand engine, but the styling mistakes are many, the regular Bonnies and Thruxtons are WAY better (all my useless opinion of course).
That said, and being the owner of a yellow-and-black TBS, I can say with some authority that the TBS is WAY more fun than the strangled twin.
Although I was tempted to trade the TBS for a T160 a couple of months back
