What changes did Triumph make to create the Roadster?

[JMichael]

Besides the exhaust and tune, what else did Triumph change to make the Roadster? Did they change the cams? I'm mainly talking about the motor. If all they changed was the exhaust and tune, they didn't do anything we previous owners haven't done to our bikes with the likes of TOR's and K&N air cleaners and downloaded tunes.​
