Triumph has established a new web site teasing two new Adventure models, one more oriented towards the street, while the other is a true dual purpose machine. It appears that the more versatile bike will be the rumored Tiger 800, utilizing a version of its respected 675cc engine enlarged to approximately 770cc.
The Tiger 800 should be light (just over 400 pounds wet), and have a larger front wheel consistent with dual purpose use.
The second bike teased by Triumph is likely a replacement for the Tiger 1050, utilizing the current 1050cc triple motor, but in a different state of tune and with more advanced electronic features (selectable ignition maps, for instance, and perhaps a form of traction control to compete with the Yamaha Tenere).
Triumph is also expected to announce later this year a new Speed Triple displacing 1050cc, but with new styling, new engine tune and updated electronic features.
We should know more about each of these bikes soon (the Triumph Adventure web site, for instance, has a countdown to the unveiling of engine and chassis features prior to display of the actual production bike later this Fall).
