Triumph are announcing a new Tiger on the 7th November. They have put out a teaser video under the heading 'Triple Technology Transformed' hinting that the new Tiger will feature a new Triple engine and new Tiger Technology. This has been timed beautifully for a launch at the UK NEC Motorcycle Show.
From what we can see on the video, the new Tiger incorporates a lot of the technology that was developed for the new Street Triple 765. This means that there will be a new colour TFT screen, rather than the old monochrome dashboard, which you can personalise. Also expect there to be daytime running lights, a variety of rider modes, and a more responsive engine.
Triumph have given the date of the launch as the 7th November 2017 at 9am CET (that's 8am GMT and 2am CST).
